most of my rejections are when girls seem very interested in person and give me their number and then flake completely on the date. Like this one girl i met at a bar seemed very into me, told me to call her so we can do something together etc etc.. I go to call, no answer. I leave a msg, no return. I run into her again at the bar and she says "hey i haevnt heard from you sweetie!" and id say i called, left a msg, no response. She'd apologize and say something like "we definietly should hook up sometime" all while smiling and seeming genuine. Ill call back and no answer, id try 10mins later since she seemed to be excited in person, then find the phone line busy... just obvious flakes.
I did have a girl a few nigths ago tell me she was rich and was going on and on about what she has and can get.. and in a very indirect way i said "lol damn girl you need to let me know how i can be down with that". So that i didnt directly say i was interested in her or wutever.. and she tells me "You cant, im all for being honest and i always go for the abercrombie white guy type guys. Im half black but never have been out with a black guy, just isnt my thing". It wasnt a horrible rejection since i didnt really make any moves on her or try to advance anything, it just came up in conversation, but still was a slap in the face pretty much.
