First of all, i am glad I aint you. Especially tonite when the wife comes home. I think it is safe to say, you arent getting any tonite!
On a serious note, to me, the siding color is the problem. That yellow/gold just does not go. Anybody can see that.
Are you going to let him know you are recording the conversation? If state law allows, I wouldnt. That is a great idea. Stay calm and let him hang himself.
I hope the best for you and keep us informed. This is like watching a train wreck....I cant look away!
