Bionca,
I am amazed on seeing how honest you are! Those tips you wrote were from your actual life? Wow! After reading the incident at the bar, I think that the man you took as a date was really insensitive. It may be that he is a half-witted person, but chances are that he was having fun insulting you. Some people are cruel right to the core.
Try not to associate with people with skin deep beauty. You are a very clever person. So, see whats in his mind, before giving up all your sensitive details to him. Someone who knows a lot about you and your neighbourhood, can inflict a lot of damage and cause pain. Dont rush, for heaven's sake. Go slow.
