Although this thread was spawned by a comment about not wanting to lose Facebook friends by revealing one’s atheistic leanings, the example I’m going to use is my wife. She is, if anything, more conservative than I.
But she works in an environment that includes a lot of liberal-leaning people, and at least one is willing to drop a friend like a hot potato because of that friend’s conservative views. Because my wife wants a smooth working relationship and enjoys non-political talk, she’s “in the closet” at work.
Less contentious example from me: I read a lot of different stuff, and some of it is material I just don’t admit to to almost anyone I know. For example, I’ve read all the Clive Cussler. When I’m asked about what I’m reading, I’ll talk about “The Brief Wondrous Life of Oscar Wao.” And it’s not a lie. But what I seldom mention is “Arctic Drift,” or “Medusa,” is on the nightstand as the next, last, or concurrent book.
So – what don’t you tell your friends about yourself? C’mon, you can tell us. We’ll keep it a secret, we swear.
