When we were first married we went round Tescos together, as Mrs Mist put things in the trolley I took them out, "We don't need that" ..... "Too dear, can't afford it"
Funnily enough we have never gone food shopping together since.
A couple of years ago she couldn't get me to go and look at settees with her, I told her to go, take a photo of the one she wanted and I would look later in the week. I went to the shop with her phone, showed the salesman the photo and asked to see it. I sat on it and declared it comfortable, I went home and said I agreed with her choice.
About 4 weeks after it had been delivered I found out I had gone to a completely different shop and looked at a different settee ! Hey Ho !
