DCS are aged 9, 4, 3 and baby. DP keeps purposely using alternative words for things when speaking to the DC. For example, he told them a friend we were going to visit had a bouncy castle in their garden. It was actually a trampoline and he was pissed off that the DC pulled him up on it and said it's the same thing
He asked one of them to pass him bog paper and moaned at them when they didn't know what he was talking about. He asked the eldest if I had finished my 'brew' and again got annoyed when she didn't know what he meant. He told one to pass him the stroller instead of the pushchair for the doll and so on.
After about the fourth instance of him getting arsey with the DC over not understanding him today, I asked why he seems to be being purposely difficult. He said he's trying to expand their vocabulary by using alternative words for things...! Don't get me wrong, I do this but I change a word in context so they can understand the meaning. For example, if we're pretending to be magic I'll say I've transformed a dog into a cat rather than changed and they'll pick up and use the word in future. If they describe something as big, I'll agree that it's huge/massive/ginormous etc.
AIBU to think the DC are right yo be frustrated with his way and that he's being unfair by moaning at them for it?
