So I was walking with my friend at the hallway & I saw the girl I kind of like looking at me. Then when we pass by again at the hallway I turn around to look at her but she hide behind her friend. Then when she came to class I was looking at her & she caught me looking. Then when she went over to talk to her friend I looked at her but then I stopped. Then later when I turn around I saw her at the back of the class & she was looking at me. But then after she left class early.

Punctuation would sure help. "You kind of like her"? Have you ever even talked to her? "Do you guys think she doesn't like me"? Well, with the info you gave, impossible to tell. But then, you'll never find out by asking questions like that on the internet. "CARPE DIEM"

A person looking at you, or not looking at you, does not tell you whether they like you or not. A person talking to you, or wanting to hang out with you, tells you that they like you, but even then it may just be friendship.

The only way to know if she likes you back, is to ask her. Only she knows what she's thinking.

I'm guessing you're both very young, 10, 11? No hurry to date. Give it time.

You guys sound very young. Sounds like two shy kids embarrassed by looking at each other.
Relax, you have plenty of time.
Talk to her, you'll know if she is even interested or not, but this all depends on how old both of you are

You will never know for sure unless you talk to the person you KIND of like. How old are you both? You seem to have caught each other's attention, what do YOU want to do about it?
