While I’m on board with the idea of it being self consciousness (knowing that there are outfits that look fine while standing, not great for sitting, including cropped tops and short skirts), I’ve definitely done it for the simple warmth when there was no throw blanket around.
You live and learn: I wasn’t aware that it’s called a pillow in the USA. What do you call what you put your head on in bed then? And does cushion (as a noun) mean anything in the USA?
I always assumed it was to prevent upskirt flashing. I’ve noticed women sitting on the Tube (where the rowas of seats face each other across the central aisle) tend to hold their handbags on their laps in a similar way.
But where else could you put your purse on public transportation? On the seat beside you makes your bag vulnerable to being stolen or forgotten, ditto to the floor and it’s filthier, and it’s uncomfortable to keep it over your shoulder/under your arm while you’re sitting (unless it had a long strap).
I’m with you, MeanOldLady. I have never heard of this supposed phenomenon before, and I can’t say I’ve ever noticed someone of any age or sex holding a cushion on their lap for no obvious reason. The only young woman I ever knew who was in the habit of putting a cushion in her lap was one of my sisters, who’d use one to prop up her book when she was reading on the couch.
I do it at my friend’s place. She has a cushion that is usually on the chair I typically sit in, and I hold it in my lap instead of throwing it on the floor. It also makes it more comfortable when I have my hands resting on it.
Sometimes I do that when I’m sitting on a small couch with other people on it. The cushion that was previously taking up room is now on my lap, plus, I can rest my arms on it so they are farther away from the other people comfortably.
