Musty smell

I left my washed clothes in the washing machine too long (again) and they've now got this musty smell to them. Musty - I couldn't remember what that word was earlier and it was driving me nuts. So now I've got to dry the clothes and wash them again. Gives me an excuse to go to the supermarket again to buy washing powder. I forgot to buy bread the last time and there's none in the freezer. Lucky those jeans arrived when they did as I had ran out of trousers to wear.
