@ruby2011:

Yeah, I think your supervisors reply to you was rude, ruby2011. As he pointed out, he felt your question was personal, okay, but he still could've been more tactful or polite in his response by answering you with something like, "Yes, she does. But it's not something I like talking about, sorry. It's a bit personal." But instead he says to you, "...it's really none of your business." Yes, a little bit rude, I'm afraid.
