What was I thinking?

We decided to go to a movie yesterday, maybe it was the 36 C. degree temp and the 96 % humidity, anyhoo I picked the flick, Hancock, cause I really love everything about Will Smith; got to the wicket only to be told it did not start until Tuesday. Without pause WTF came rolling off my tongue. Husband and elderly neighbours gasped...so I said it again, WTF. What would you have done? Was I out of line? We saw Incredible Hulk instead.WTF
