This is from a stalker who has become a friend(ish). We have been through some tough times, from the day he commented quite randomly on my picture, to summarizing my facebook page, to sending me emails to remind me to reply previous emails and complaining that i take too long to reply and that makes him think, "gosh i hate her so much." Yes there are people out there who get very emotional if you do not reply their messages in under 24hrs. I also have a best(ish) friend who was a pro-stalker, i call him Top wanker because he can be a wanker of the highest order, but he's still fun. Its been a year and we still haven't met, in person. I know i walk in pretty shark(y) waters. Swim actually...
