I woke from a dream. :) I'm guessing this one was spawned by a discussion I had with Mr Music about carrying his house key at all times.
I was doing some sort of research -- actually, I think, a doctorate -- into what people carry in their pockets and how it varies across occupations and how it has varied throughout history. And the research was expanded to include things like the cloth pockets women wore in the colonial period, and purses (pocketbags) and even small backpacks.
The apparent focus of this research was how it seems to have changed in my life. My Dad carried a wallet, some change, his keys, matches, a fountain pen, and always a cloth handkerchief. I remember my Grandads also carrying off-white pipe cleaners that came in packs of about 30 with a paper band around them (Dutch something?) even though I don't have any memory of them smoking pipes. I will have to ask my Mum about that one.
I don't generally have much in my pockets -- just a fidget toy and a lip balm --but rely on a purse or coat pockets for the rest. And here's a fun link if you want to see into other people's pockets.
So I am curious. What do you carry with you wherever you go?
