Lighthearted, but reoccurring argument with my DH over what a jumper is.
Context: I'm doing a wool wash and ask if he has any Jumpers to go in (the only things he has that are wool), he says no. Then picks up some washing, which includes a jumper, but he says it isn't a jumper...it's a t-shirt because he doesn't wear anything under it.
YANBU: a jumper is a long sleeved top made of wool (although I wouldn't argue with someone calling a similar non wool top a jumper)
YABU: even if it is a long sleeved top and made of wool, if you don't usually wear anything under it then it's called a t-shirt
We're in the UK.
