Around my line of work, we refer to those who don't make mistakes, as though who "don't do anything"....
I figure if I make a hundred decisions a day (starting with what underwear I put on in the morning) and I get 98% of them right, I still made at least 2 mistakes. Whether that is the socks I put on, or the breakfast choice I made, or something I said in a conversation, it is still a mistake. Some of them don't mean to much, but some of them do. I learned a long time ago I was not perfect, and neither are those I work and play with. We each have "genogram", thats a nice way of saying we all have things in our past that make us act the way we do.
Now I know you weren't thinking I was perfect, if you did there's your mistake right there....[>:][X(]
