Since childhood I have slept naked.
My mother used to tell me stories of how she would swaddle me up in all my babyclothes and put me to bed in my cot.
She'd come back in a half hour later and I had managed even as an infant to rid myself of all my clothes.
All through childhood I would be dressed in pajamas, which I willing wore around the house, but as soon as I was in bed I took them off.
She eventually gave up.
None of my siblings showed the same disdain for sleep wear.
In the summer moths I sleep naked on top of the bed not even covered by a sheet. Like a beached whale.
Winter, I do tolerate a lightweight duvet.
