Admittedly, they used to bother me. I realize looking back on it that I was usually being pretty arrogant about it (not that anyone else is being that way if it does bother them, it's just the way I felt about it). Additionally, I realize that when I pick someone apart on message delivery I am most likely going to miss the message content.
On the other hand, it is a little more difficult to swallow when it comes from someone who isn't usually sloppy. Also, my tolerance increases nearly to limitless when I'm talking to someone about an emotional issue.
Anyways, I think that its not to important how someone say something its most important what they are saying....right?
