We used to live in a house that had a freeloader "guy on the couch". I loved grinding the coffee in the morning as I could see his sleeping frame jump when I started the grinder. Now I don't want to wake any sleeping children (Max's room is next to the kitchen). USually I wrap a towel around the grinder to muffle, but we were out of towels so I put an oven mitt over it. That worked perfectly, reducing the noise to a dull whirr...
