The Sons subscribe to the "toss your used bath towels in a heap on the bedroom floor, so they get moldy and the dog pees on them and Mom has to wash towels all the time" philosophy. This means there is almost never a towel hanging in the bathroom, when one of them needs a towel.
Some of the Sons have learned to check for a towel, before they start their shower. But Son #4 almost always realizes he's towel-less, as he's standing in the tub.
This can require a mad dash to the linen closet. But this morning he was in the bath early, while the older Sons were still at home. So he called to Son #1 to hand him a towel.
Son #1 tossed him a shoe.
"A TOWEL, PLEASE."
Son #1 tossed him a pair of boxer shorts (clean, I know, because I can see that he fished them out of the depths of his clean clothes stack, in the living room).
"COME ON! Just give me a TOWEL."
"You can use it like a towel."
He then handed him a Christmas-themed dishtowel.
At this point, Son #2 chimed in with his traditional words of wisdom.
"In future, you should get your own towel, before you go into the bathroom."
Fortunately, Son #2 serves up his snark with kindness. He handed him a towel.
"But this is the last time."
