Even though I never heard of anything this nervy, I am not surprised it happened. I always heard the constant appeals for money to pay for the COs expenses and also appeals for people to give dinners. But never this. Personally, I would be ashamed to ask somebody to do this for me and I wash my own undies in the sink. I would make it my business to ask around for a decent laundromat to do the big stuff.
Maybe, just MAYBE I could accept the brother HIMSELF asking to use somebody's machine but he would do it himself. I think it is rather personal to do laundry. Besides, who the hell wants to see his dirty drawers? Not me.
