failure to communicate

I won tickets to a Sabre hockey game tonight. B came home from a bike ride. Went to shower. I am waiting and working at the computer. We are going to dinner first. Leaving at 5. waiting waiting waiting....then I look out the kitchen window and there he is in the car. Has been there awhile. I said why didn't you tell me you were going out to the car. He said why couldn't you look out the window and see I was out there. More words were spoken then quiet.
