Woolly Hats indoors

Once upon a time you could tell a pretentious git because he/she was wearing sunglasses indoors for no apparent reason. Happily this strange activity has mostly died out. But now there is a strange new trend in the wearing outdoor clothing indoors scinario- woolly hats. What's that all about?
Woolly hats are what you had to wear on the way to school because your mother got the neighbours to spy on you so that she would know if you didn't.
Woolly hats are what old men wear to keep their heads warm when all their hair has fallen out. Woolly look cute on toddlers waving sparklers in the dim light of an (outdoor) bonfire.
How on earth have these saggy bags of wool become a fashion item? Ad why oh why do people insist on wearing them indoors?
I can see how earing a woolly hat indoors would have its advantages, no need to brush hair, wash hair or even to have hair, but surely it is not comfortable in a hot sweaty bar?
The worst is people with long hair wearing 'beanies' remember those dodgy party hats where the hair is swen into the rim- it's them, it is, it is. And what happens if they ever pull. Do they get to s softly lit room with a lovely person and remove the hat to show a squished up mop of sweaty hair? Or do these people have sex with their hats on? Are they attached? Do they need to be surgically removed. And wear will it all end? Will we be wearing gloves indoors next? Or will it go the other way and will people end up in Waitrose in their Pyjamas?

mMMMMMMMMmmm?
