AIBU to think that there should be some sort of mandatory punishment for people who use a bread knife for anything other than cutting bread? I think a short, sharp flogging would be punishment enough. For instance, this morning someone (DH almost certainly, he's a known knife-related CF) used it to spread marmalade.
And also, not punishable because some people genuinely can't help it, I think that learning to cut even awkwardly shaped loaves of bread in a vertical line is a necessary life skill. And any grown man (or woman, but in this house it's a male problem) who can't should be ashamed of himself and have to wait hungrily until the resident straight cutter finishes her lie-in to have morning toast.
I hardly ever start an AIBU thread, but I'm feeling a bit masochistic so am up for the character assassination that will surely follow. The bigger the logical leap in the assumption about my personality the better, 'controlling' and 'unpleasant' are too obvious, so I have already done that for you.
