Oh, I see. Well, without knowing very much about the situation, I would say that being truthful will usually make you better off in the end, if you're able to have a conversation with them. Every family is different, but sometimes they'll surprise you in a good way. My ultra-conservative "everyone who is different from me is wrong" father was able to accept that my sister is a lesbian, because he loves her just a little more than he loves his closed-minded ideas. Even if they're going to get upset, let them get upset over what is the truth- that way, you at least give them the chance to come around one day, maybe.
