ah, the secret crush on a sexy thang of a women, yep i think all young men had one at one time or another, slip a note into her locker but dont sign your name to it, in the letter tell her she has a secret admirer. but make sure your around to see her expression when she opens the locker to read the note.
keep writting her love notes / letter /poems ..then when it's driving her mad that she don't know who it is...then give her small hints it's you.
