We had a christmas dinner with my parents and brother on Christmas day. My brother is back from uni and so has been staying over at our house. As a thank you this morning he cooked me bacon sandwichs in bed. Dps family came over for a meal today but my brother used the bacon we had intended to use for pigs in blanket. When we were preparing Dp noticed he'd done this and went mad calling my brother a thick cunt and saying how he was a moron who had ruined the meal.
AIBU to think that Dp was stupid (the fact we served sausages and no bacon had little difference on the meal) and completely out of order for speaking to my brother like that.
