Yeah, like the others suggested, people seem to decide pretty fast whether they are going to like someone or not. I would guess there is another reason they are after you, and this is merely a handy outlet. On the other hand, this profession, like most other well-paying professions, seems to draw two kinds of people, those who truly like it and get a kick out of it, and those who are only in it for the money and would never dream of even carrying on a conversation about it on the weekends. These people tend to hate their jobs, so if they see you enjoying it they may be jealous that you truly enjoy your work.
