Twenty-five years of marriage ... net result:
Conversation before husband goes to store:
"And we can have macaroni salad."
"Okay ... just a sec. We have relish. Um ... Yeah. We have mayonnaise. Just get the macaroni."
Conversation after husband goes to store:
"We got this because we needed it," ("it" is a pie), "and," (hand back into grocery bag) "I got mayonnaise because I don't trust you."
Hmph! I've put the extra mayo in the cupboard now. We already had mayo. I have no idea why he wouldn't trust me! Really. No idea at all.
