My mom often has this habit of just wearing whatever she finds in and around the house. Clothes, shoes, whatever it is, she figures it's placement on her property makes it part of her domain.
So she wakes up and turns to me, pointing at the shirt she's wearing. She says, "is this shirt yours?"
"No," I answer.
"Is it your brother's?"
"Oh. I don't know whose shirt this is. But it's really soft," she murmurs as she falls back asleep.
