What is a good comeback to, what you say alison, i just don't care.?

People like that, they're just not worth bothering with. You're right to ignore them, they eventually just give up and find someone who'll react. Still, if you're after a reply you could always try saying 'you think I care what you have to say? Why are you talking to me?' and try to talk to someone else. Just make sure you don't get worked up about it would be my advice. Don't let them know you care or that you've even noticed or thought about it. Play it cool... Good luck!
