I know some people do this, and this is a problem I have to deal with the fallout of often. I tend to say what comes to mind before thinking about it. Most of the time I'm fine, but sometimes I'll blurt something out and then 15 minutes later I'll be like "Why the FUCK did I say that!?"

Like this one time, at band camp... Except it wasn't at band camp, I was speaking with a workmate of mine, my manager no less. I was only half listening to her while we were speaking about the media and newspapers and the like whie we worked. Here's the record of what happened next (I spoke first):

"Bah, I don't read newspapers or listen to the news. 99% of it is sensationalized so people will watch or read it, that's how they make money."

"Yeah, but do you read any of it at all?"

"No, and I especially hate the horoscopes. They're even more full of shit than the rest of it and so are the people who read them."

"..."

"What?"

"I read them."

Needless to say, despite the fact I was only there for two weeks before they raped my contract and shat on it for all it is worth, I pretty much destroyed any chance of continuing the job besides that. 15 minutes later while I was getting something out of the freezer, I was like "Why did I say that..."

Yes, I put my foot in it and I do it often. Just thought I'd share this little story with you so you can have a bit of a laugh.
