We were talking, SWMBO and I, about choosing something or other in some posh shop and she wanted one thing and I disagreed and said to her that it should be my choice because she should realise that I have a much better sense of taste than she does. The shop assistant was ready to duck when the reply was "what the hell gives you that impression!" I held up my hand to stop her and I just said that it was totally obvious and I could prove it any day at any time. She said OK then do so!
I just told her that it was obvious and the proof was ------- I chose her, look who she chose
That's one argument won
