I notice a lot when I'm out and about people who haven't dried their washing properly *, and so it has that sour musty smell washing gets when it's wet too long or isn't getting enough air. To me it's a really "loud" smell, and I just wonder if people don't notice it? Or maybe don't care?
*disclaimer: I'm not critiquing people whose circumstances mean they can't dry them any other way, I have been there myself, but the people who could dry it correctly but don't.
It just puzzles me.
