What is all this? If Him Indoors dared to open my mail, never mind deciding what was rubbish or not, he would be neutered tout de suite!
It sounds to me that you have some houses to be put in order. Why do your spouses go through post addressed to you? If our post says Mr and Mrs P. Galore then fine. I have noever opened his post, and he would never dream of opening mine. This is nothing that we imposed on each other, it was ever thus. He would never rummage though my handbag, nor I through his wallet.
Maybe that he remembers that I still have my mother's kitchen poker. She would never have stood for that either. So I ask you gentlemen, have you ever done the same to your wives?
