If she luks at u smile at her
if she smiles at u wave at her
if she waves at u smile and wave at her
if ur close to her just kinda joke around and ask hows ur love life? then ask oh rite so who do u like. and she says nothin say I will tell u if u tell me first pinky promise.
or just ask her straight ou t u wanna go cinema, library, bowling etc. on saterday?
hope I helped ~ xXx
