What are something's a girl does that shows she likes you?

It depend on the girl honestly. We usually smile a lot, and laugh to make you know we think you're funny. She might touch her hair a lot, to try and make it look nice or I've used that tactic to bring attention to y hair if it looks good ha. She might speak in a higher tone than normal, it's a natural thing. She might find little excuses to talk to you, to touch you in small ways like hug you, "accidentally" bump your arm. She'll want to hang out, or if her friends look like they're messing with her when you're around that's a pretty good sign. And extra information: if you think she likes you even a LITTLE, you should do something about it. Girls that like you won't wait forever. Sure, they'll like you, but if they start to think they have no chance they'll be upset and let down and try to forget you. Good luck.

You'll catch her staring, defending you, making sure you're okay, act a little cheeky. She might even come off defensive, and willing to not let her guard down. We like small compliments, like, "You're hair looks cute like that."
