How can I act toward shy girls?

I was a shy girl, I wasn't snooty or stuck up just generally very afraid of talking. Seriously, it felt like th most impossible thing to do. I wanted to talk, I had things to say, I just couldn't muster the courage to do it! Not for anyone, not my parents, friends, teachers. Only one of my friends stuck by me, because he knew I wasn't scared to laugh. Talking was so very hard and over whelming, I can't even begin to describe it, but one day I sat down and asked myself:
Am I happy living this way? No.
Do I want to go through my life with this obstacle always in front of me? No.
Do I want to have friends and be heard? Yes.
So I set out so determined to change, so willed to overcome my weakness, that I did.
Sure, it was really forced at first, but it had to be, and after 6 months or so it became more natural. Can't tell you how surprised my friend was to hear my voice, haha!
Now I talk to much ;]
Sure sometimes I get the same anxiety but its really easy to brush off now. =]

I'm not a "shy" girl, but I definitely can be. Plus, I have a friends who are SUPER shy. You have no idea. Anyway, to answer your questions (your many, many questions):

1) They (as in the shy girls) normal act completely normal around the guys that they like. They normally ignore the guy to the best to their ability. They pretend that he's not even there. It even might take courage for them to start a conversation with their crush.

2) It's easy to confuse a shy girl with a snooty or stuck up girl. Sometimes they even are. You can't know until you get to know them so try hard not to judge.

3) They are scared shitless. They don't know what to say, how to say it, or when to say it. They sometimes think that the conversation will go horribly. There will be awkward pauses in which they will be asking themselves, "Ummm. Now what? " Normally, the guy has to start the conversation with a shy girl. It's hard to keep the convo going at first, so don't give up right way, when she seems bored. She probably isn't bored. It's her nerves taking over!

4) Hell yes. Girls talk about their crushes all the time. Half of my friends don't even talk to the guys that they like. They might sit next to them in their Algebra class or they might be on the same bus as them. Some of my friends gaze at their crushes from afar. It's a terrible thing truly. But then. Oh but then. When my friends and I are talking, they will be talking about even the slightest amount of human contact they had with their crush, even if it's just a simple question like, "Can I borrow a pencil? "

5) The "What should I say? How should I begin? When should I break the ice? " question is always the most difficult to answer. The fact of the matter is that it really depends on the girl and her personality. What are her interests? Do you share anything in common with her? If you want to start off at a super easy topic then here are a few:
-school
-a class that you both have
-last night's homework
-borrowing pencils
Then you get to some "deeper" stuff:
-what you did over the weekend
-how much homework you had over the weekend
-school events coming up
-teachers that you hate or really like
-a break that's coming up (spring break maybe? )

Well, I hope this helped you out. Message me to tell me how things worked out. Good Luck!

Aww. for one. I'm a very shy girl so I know this stuff.
A:
-Girls act more shy around those they like because they get more scared,self-concious, shy.
-Not often they do. Sometimes if they are offended or if they want to intimadate you.
-They are silent because they don't want to say anything that would embarrass them more then they do just by being themselfs
-They usually do talk about them to their friends or they think about them ALOT
-idk what I say -_-
-Sometimes if we are in a bad mood or they just don't want to admit their liking to them.
-once again they don't want to admit their likeing to them
