@Wherehaveigone26, sorry, but I wouldn't have gone out just for bread either. What's the point of buying something you're not going to eat? It's exactly as @Tart Cherry Jam wrote above.

I do the grocery shopping. My wife will add things to the list that she thinks I need. It goes like this:
WIFE: "Get more guacamole"
ME: "Are you gonna eat it this time?"
WIFE: "No, but I noticed you've been eating a lot of it lately, and we're getting low."
ME: "The only reason I'm eating it is because it's expired and I don't want to throw all of it out. Just put things on the list that you need."

Having written all that, it seems like you need a break, and it seems like your husband is tired and depressed. But that free observation is worth no more than what you paid for it.
