Camping at the moment, the toilet building is about 3 minute walk from where we are pitched. My husband tends to wake up middle of the night and - instead of going to the toilet - he uses the kids' plastic bucket to pee into. He thinks it's normal and I am completely unreasonable to think it's a disgusting habit. He's also mad that I told the kids about it, as they are now refusing to use the bucket. AIBU?
