Very Random Thought

I was typing a couple of emails this morning and realized something - I use the "!" a LOT! I mean, I don't even try to do it, it is just a habit!! Maybe it is because everything in my little brain is just so exciting to me that I feel it needs a "!" at the end of it!?!?! And, if it is really funny or a good thought, then it deserves "!!" or "!:)". I know it isn't good to use one at the end of every sentence, but a "." is just so boring! I'm at a loss of what else to do!!:)
