Try expressing your feelings next time, if after you tell him to leave you alone & then he Continues THAT is harassment. What it sounds like here is you were victimizing yourself after your rude statement when someone, who you assumed wanted to sleep with you, asked about Bread Hahahahaha. If you don't expect to be hit on maybe you'll notice kind conversation, I bet if it was a 'hot guy' you wouldn't be ranting. BTW, people will usually help a woman over a man. Warped social reactions don't make you right.
If it wasn't BEFORE....
