Somebody has been in your locker!
Not that anything is missing, no - but there is something in there that wasn't there before - a hand mirror.
It's shiny, it's gold, and it's more than just a tad... well, feminine. Attached to it is a Post-It note, upon which there is flowery, feminine handwritting that reads:
"I'm leaving this very special present for you in memory of the very special night we shared together. I'm sure this gift will be... especially suitable for the occasion."
For a moment, a cold chill runs down your spine, and you glance nervously about. After all, you are strictly a "love 'em and leave 'em" sort of guy, even if that does cause some... friction with the girls you've slept with. Given how fast-and-hard you dump them after your immediate desires have been met, you've never had to worry about any of them being 'clingy'... at least, not until now, maybe.
