Polls: Flirting

Hi girls, I would like to ask for your opinion on the following. Recently I was attending a get-together with other people, one of them being a girl I've had a crush on for a very long while.
We've known each other for years and have become more comfortable with each other over the last year or so (but nothing major, to be honest).

As we dined, I happened to discretly look under the table and noticed that her feet were pretty stretched out, almost within range of my "personal space". No touching was taking place, as when I usually sit and dine, I tend to keep my feet tucked in, almost directly below my sitting area. We were facing each other, accross the table.

I decided to go a bit bold ("bold") and moved one of my feet in her direction, hoping for some contact to take place (waiting for it).
Not only it did, by her foot touching my leg, but shortly after she pressed her foot onto mine, almost as if wanting to understand whose foot it was. Not only because she might have realized the only foot aligned with hers would be mine, but also because she had only one other person sitting at one of the tops of the table. As I was sitting accross the table, I would assume it might have been fairly easy to tell it was me.

She left it there touching mine for a while until contact eventually broke as the socializing progressed, etc. Recalling the situation - I dunno, maybe we held contact for a couple of minutes, tops. No caresses were exchanged, just the touching itself.

What would you make of this? Something? Over-analysis?
When a woman's foot touches a man's leg/foot, does it usually mean anything? Or could it have been something absolutely natural of her? She's not the "touchy" type, I'd say.
Thanks for your opinions!

So I was coming home from a nightclub with my mates and we decided to go get some food because we were hungry, whilst in the resturant i spot this pretty girl (solid 10/10) inside sitting next to her mate eating some food. So anyway I talk to them, ask their name an introduce myself etc, and midway through convo I remember the pretty girl i liked took her phone out and I saw that she had her front camera on and it was angled where me and her where in the photo, so she must have took a sneaky selfie of me and her (but she didn't mention anything about the photo and it was a sly photo where I only recognised last second that she was taking a photo). But the thing i'm wondering is why did she do that? Girls what would be your reason to do this?

1. Is it just something you would do to put on your next snapchat saying something like "random guy talking to me in resturant" or took it just to show your friends the next day of a how some guy tried to hit on her and her friend.

2. Interest in me was there and wanted a sneaky photo so she remembers what I look like for later memory if she sees me around (A lot of girls say i'm good looking so i'm not sure)

3. As it was late at night she thought i might be someone treatening so took a pic of me incase I harm/threat her or her friend and can easily report me to the police showing them that photo if I did.

What do you think the reason was? Any input will help me out so much :)

If you don't know what a line up is, this is what it looks like:

Young ladies 18-early 20's: I'm 19, and have a condition that made me lose scalp hair, a lot of thinning happened and I really have no choice but to shave it skinhead, people say I pull it off well, I'm paler and skinny but my face and headshape work well with it. But the big concern is young women, I've read so many stories of guys on the Internet who lost hair young and say forget about the pretty girl. I don't want it to be true but there are a lot of them out there. And truthfully I admit looks matter to me, I have higher standards but it's something I take seriously I'm not some player I only need one attractive girl in the end, so what I mean by saying this is; I don't blame girls for wanting an attractive partner either, I'm just wondering if no hair young makes you unattractive. I just can't imagine an attractive girl who obviously has plenty of options most all if not all have hair, would choose the bald guy. So young women, could you date a shaved bald young guy, keep in mind it's full Howie Mandell skinhead not even a shadow. I don't want feel good answers I want the truth, and before you answer picture if one actually approached you and asked for your number or complimented you to gauge your true reaction on the spot. I appreciate honesty, thanks for your time.

So basically, I've been recently hearing everywhere that studies have shown that a man who smiles is likely to be less attractive to females. Smiling is perceived to be a feminine trait which makes a man appear to be less dominant. This is a huge problem for me because I'm usually an energetic positive guy who can't help but smile when talking to a beautiful lady. But then, I have heard some females say that nothing is more sexy to them than a nice smile. I do not want to become someone I'm not and try and act like a badass mysterious macho man with no feelings. But anyways what do you women think? Is smiling a turn-on or turn-off. Honest opinions please.

To give you some background info, I have recently lost over 120 pounds of weight this past year and have been bulking up with muscle. Since my new muscle mass does compensate for much of the fat that remains I end having a pretty good figure, considering what it used to be. I've recebtly decided to go out and try and find a girl, since it is getting rather boring being alone in college. The last 4 I tried turned out to be lesbians heheh. (Figured out due to asking, specific lgbt stuff they had etc) I guess thats the risk you run when you like short haired girls. After failing with the fourth one, it was a quick realization. I realized that a really attractive (and straight) girl had been eyeing me all class. Thinking back it was subtle at first before class when I kept catching her giving me quick scabs when I stretched (sore from gym). I didn't think much of it until I kept noticing that she was looking back at me. Turning her head so that she could see out of the corner of her eye. At first I thought she was looking at someone else, but there are no other men in our desk row. This happened a few times until we finally locked eyes for about 5 seconds before she looked away again. As you can probably guess I am apprehensive considering what has been the norm when I approach women and how unbeleivably attractive this girl is. So my question is ladies, do you think she is into me? And should I appeoach her?
