This is why I have to have a job: Because left to my own devices, after a week there will be no more mugs in the cupboard because I will have carted them either to the bathroom or the living room to abandon them to their mold-filled fate.
This was a particularly horrible habit* in high school when I would take glasses of orange juice to my room to finish curling my hair. I had a lot of mold colonies floating in those glasses.
