Do I Know You?

What is with Jews feeling the need to say HI just because I'm Jewish? Excuse me, but do i know you?
Take this afternoon, for instance. Trying to enjoy a leisurely lunch with SlutBag in Smelly Restaurant. Packed by Jews all trying to buy a tuna sandwich which is made by WomanBehindCounter cutting open a Lenders bagel, scooping up a spoon of tuna, and covering it with bagged lettuce. She doesnt even bother getting a fresh head of lettuce to cut up. But whatever. Moving on. Walking out the door, squeezing past too-fat Jews on their way to packin more on, I hear SlutBag behind me, "You're such a ho. Say hello to her!" I step outside and turn around, "Say hello to who? i dont fuckin know anyone in there!" (Jewish lady eating outside gives me the evil for dropping the F-bomb but whatever. Fuck her.)
SlutBag: What are you talking about? We went to school with her!
Me: so because we were in the same grade with 100 other girls 8 years ago, I have to say hello to her? I dont think i ever said hi to her when we were actually IN high school. I dont even know the bitch's name.
SlutBag: ur such a ho.

Yea, what else is new.
