Aw, give her a break, now you know you would die if she wasnt around.
Izzy can be a little jerk sometimes too. He did the same thing this weekend but did while I was around. I was in and out of the house that day running errands etc., and I guess he was annoyed and peed on the floor right in front of me! It took all I had to not put him on a door step with a "For Sale" sign!!

I feel your pain, sometimes they have their moments like we do!
