Name changed as potentially outing (but potentially not!) Pom bears, screaming at the sistine chapel, etc etc.
Chatting with a friend and suddenly remembered that as a kid in primary school, I kept my stuff (exercise books, pencil case, lunch) in... a briefcase.
A black leather briefcase with a combination lock.
Didn't wear uniform, and this was the mid-90s, so I would have been a 7 year old with frizzy blonde hair and big glasses, wearing leggings, an oversized t-shirt, big white trainers and... an adult-sized black leather briefcase.
It's JUST occurred to me (at the age of 33) that that is SERIOUSLY WEIRD!
Asked my DF what in the world we were thinking, and why I didn't just have a backpack like a normal kid, and he says it WAS normal in those days – but I don't seem to remember any of my peers also having a briefcase like someone working in the City 
What did you carry your books in as a kid? Any other briefcase enthusiasts?!
