Thank you so much for all the responses. I guess trusting my instincts is what I need to learn to do! And tell someone to back off regardless of whether I think it will hurt their feelings. I guess I am really out of practice, I don't get approached anywhere much these days - getting older is no fun. I was wondering if it is just that I am not used to getting approached, but I think I should trust my instincts on this.
Thanks again.
