when you climb between the sheets at night? Does it differ when you're alone as to when you're with a longtime partner or a new partner.
I've completely dumped pyjamas and all forms of clothing for the last thirty years or so, and it has become more than a simple habit. One night I was out on the town and couldn't get home, forcing me to sleep on the couch with a person I had only briefly met but who took pity on me. She woke up first (the couch was in her combined bedroom / sitting room) and went to the toilet wearing nothing. I woke up as she came back into the room. 'I see we have the same taste in poyjamas' she commented, not even slightly phased by our nakedness and the fact that we hardly knew one another!
