If your girlfriend ruined your favourite shirt, (if your boyfriend ruined your favourite dress) how would you react?

My friend just called me upset, because her fiance just did the laundry for her lol
and her favourite sweater dress shrunk into kids' dress size lol she was like furious mad hahaha lol but I think it is still sweet that he tried to help XP but yeah I might be sad of course lol.

How would you react if this happened to you?
would you be really upset? :P
