Sure signs a girl likes you (like a crush)?

[LookatDuhDonkay]

Quite frankly, I'm a bit embarassed to be asking this question but what are some CLEAR physical signs a girl is into you and not simply looking at because you're speaking up in class?
I've read into some wrong signs before lol

Every girl is different. Some girls refuse to look at you when they like you, they avoid you, their friends tease them when you're around, etc. Other girls will flirt a little, make lots of eye contact, and talk to you just because.

She makes a point to touch you in conversation, she looks and talks to you differently than other guys. She likes to talk to you, you might catch her looking at you, she pays more attention to you than to other guys.

Don't be embarrassed, its cute, anyway, if she smiles at u wen she sees u, or acts a bit different wen ur around, more shy, sweet, outspoken, etc.
