One sunny Sabbath afternoon Shlomo and Moishe, two old friends, meet for the first time in a few years. After exchanging the usual pleasantries Shlomo says, "Moishe, people are telling me you don't go to synagogue anymore. Can it be true? You no longer believe in God?"
Moishe looks uncomfortable and quickly changes the subject.
The next afternoon, they meet on the bench again and Shlomo persists. "You must tell me Moishe. You don't believe in God anymore?
Moishe replies, "Here's a straight answer to your straight question: no I don't."
Shlomo asks, "So why didn't you tell me yesterday?"
Moishe shocked to the point of disgust, exclaims, "On Shabbos?! God forbid!"
