You would think that we would all have a certain amount of similarity about this, but no.
I remember taking a train through China back in 1989-90, and it was a long distance train. All the Chinese, as soon as they got on the train, changed into their jammies and stayed in them till they got off. (While smoking heavily)
The Catalans? As soon as they are home for the day, they get in their jammies. Aparently everyone does it. If they're at home, they're in jammies. This may explain the strangely high prices for jammies here too.
I don't know many folks in Canada who do this. Teenagers, maybe yes, not when they get home, but not wanting to get out of them in the morning.
Do many of you change into jammies when you get home from work? I mean, I am told, that they are cooking and eating dinner in their jammies.......
Not exactly a big deal, but odd differences.
