Staying with my lovely SIL at the moment and went to make myself a sandwich (we have the kind of relationship where it’s totally fine for me to do this). I fancied peanut butter, but when I looked, there wasn’t much left in the jar so I went for cheese instead because I thought it would be rude to finish the peanut butter. Thinking about it, is this a thing, or should I have just slathered peanut butter on my bread without a care in the world?
