If u know that u are not the only one to have a crush on the guy u like don't start treating it like a competition. be the gerl that's not head over heels obsessed. don't do things like leaving a creepy stalker note in his locker,or every chance you get stare at him/sit next to him/talk to him in an over flirty voice because this creeps them out. and most of all never clean his locker/notebook/car because it takes part of their manliness away. if u let him know that u like him sutely he will start going for u.
