I try not to. I find it very unattractive. When I do get very upset I do curse, but otherwise I don't. I heard a girl on Satellite Radio calling in and saying the F word every other sentence and it sounded very cheap. The other day I heard someone say "it looks like it gonna fucking rain". Why would you say this to a stranger? I was tempted to say "you sure do fucking curse a lot" but I didn't.
