"Alice, where's my jockstrap? I needed it for today's match," whined the professor's son Billy.
Alice rolled her eyes, and set down the decanter. "When did you put it in the hamper, Billy?"
She had done laundry yesterday.
He looked nonplussed as he checked his gym bag. "Oh, I guess I forgot to put it in the hamper. Could you wash it now?"
Alice rolled her eyes again.
"Alright, but you're 21 years old now, and should probably learn how to wash it yourself. Come over here, there's wash sink. I'll show you how to do it."
Alice walked over to the sink, and Billy joined her carrying the distastefully stinky jockstrap away from his body.
"Here."
"Well, it's simple, Billy, first you run the water and fill the sink like this. Then add some liquid detergent, but you can use powdered, under the tap so it gets sudsy." She grabbed a plastic squeeze bottle marked simply 819 Concentrate and squeezed the amber liquid into the sink. It suds up nicely, even if it isn't really detergent.
