ok so my friends think this guy likes me but im not sure and i kinda like him so what do i do?

just casually say hi and stuff in the corridoor (im assuming this is at school?)and if a conversation starts, then just let it take its course and see where you end up!!! :)
yes, i did spell corridoor wrong.
no, i dont care.

One never trust what friends tell you. Two if you want to know if he likes you ask him. Three don't ask unless you're sure you want the answer. Four take a deep breath, I'm sure that if he likes you he'll tell you and no one else, fyi.

This is good coz I'm a guy.

We like confident girls. Girls who ask us out themselves and not have their friends do it. Also, we like girls who come across as fun so while doing it dont just stand there act comfortable.
So just do it :)

Never trust your friends, when you ask him if he likes you and it turns out he doesnt... it will suck.
