Luckily I was explaining this afternoon to someone (can't remember who) how my hopeless memory means that I write everything in my diary (buy lettuce, check emails, dead-head rose, replace loo-roll), so opened my diary to demonstrate and realised I had a dental appointment this afternoon. 

I made it home for the toothbrush, made it to the dentist, made it back to work. Phew!

Meanwhile, inexplicably, some people have poise.
