Recently I've been in the situation where I've had strangers ask me sorta personal questions and I've really wanted to tell them to 'Fu*& Off!' However, given that I'm in a formal environment (i.e. summer office job), I don't consider even the phrase "That's none of your business" to be polite. So, in the interests of retaining civility of co-worker relations, could you please help pick out some more appropriate phrases. So far I've been bumbling by on stuff like, "That's a little personal isn't it!" :b I need better material. Help!
