After washing up for bed I put on my sleep T-shirt and then I realized I had absentmindedly put on my exercise T-shirt, so I took it off and put on my sleep T-shirt, but then I realized I had absentmindedly put on my everyday T-shirt and I took that off and put on my sleep T-shirt.
Then I thought of a recent post by John Scalzi in a similar situation where he talked about needing to sit his brain down and have a conversation about how T-shirts work.
