Jaime, have you ever been in a situation in which you can make that statement an accurate observation?
I am not trying to belittle you at all but I do find it very difficult to back your statement up based on your somewhat limited observations of this individual.
Then again, I'm sort of doing the same thing you are ... but in a somewhat more positive way.
