Wait until you are a 20-year-old guy !
NO
They act normal..?!?? They act just like their true colors. They do stuff silly that they would be embarrassed to do around their crush
By believing in yourself
Flirting is not a legal concept. Anyone can flirt with whoever they want. You can not talk to a minor about sex though unless it is education where you should have permission from the parents. But that is of course not flirting.
Object permanence. A 1yr old is developing the idea that if something is not seen (ie your face) it still may exist. It's exciting to find the face is still there. A 7 yr old already knows your face is still there and would rather play on his DS :)
Umm...it depends on their personality...and also if the ten year-old is a guy or a girl...
They tend to blush or laugh at you a lot and/or avoid you or look at you all the time. They may be themselves when around a guy they like. It depends on if your confident.
Just be yourself. What's the point in having to act like someone you're not just to get a person to like you. Eventually, if you act like someone different he's going to notice. So you need to just be yourself and he doesn't like that then go find another guy. You need a person who loves you for you, not for someone you're not.
No, because a 13 year old is supposed to act like a 13 year old, a teenager.
be yourself
No, but you shouldn't act on it.
desperate
like a 2 year old baby
They like to act like they're grownups. Trust me i know I'm a nine year old.
Talk to the guy and let him get to know you.
The 10 year old will most likely act like they normally do
i he wants to
