I mumble a lot. It isn't great, and, for whatever reason, I don't do anything about it. One of my friends tells me that I do it all the time — she's right — but I'm probably never going to change.
She also always mishears me, which makes sense, but she ALWAYS hears something way funnier than what I actually said. Sometimes I get away with pretending I said what she heard, but other times I just can't.
But, I guess it's just a fact of life that sometimes things seem cooler than they really are.
