What do you wear when you sleep?

Replies to self - that flannel gown with hood is more for hanging out in, around the campfire or the computer.

Pyjamas, I remember those...

I have a friend who insists he wears only a condom, even when he's alone. I find that puzzling.

Did you ask him where he slept at night? Might be the train station!

nothing.

unless it's "that time of the month" in which case I have no choice but to wear undies.

or if someone is staying at my house, then I wear a tee and undies.
