Like the title says, i mean seirously, I really can NEVER be myself because whenever i say something from the top of my mind you get creeped out, and it's usually on the tiniest stupidest things. That's messed up. Why do you get creeped out so easily?
I forgot to mention that i'm nothing close to be a creep. I'm like the nicest, funniest (always smiling as well), and most confident guy ever.
or for a more detailed answer, we don't know you, we don't know if we can trust you, and we can't be sure you're entirely joking, because we're wary as to whether or not you actually would want to do something to us, and also likely, you just have a creepy attitude.
Women are (understandably) suspicious of men they don't know, especially if they approach them in a way that is more friendly than normal. It's creepy because it seems like they have ulterior motives (not saying that you do, but a lot of guys with bad intentions cover them up like this). Being nice is a good thing, but being too nice is creepy. Does that make sense?
