Dearest Mum,

I know you've been concerned, but I've done quite a good bit of research, and, honestly, I think it's really rare for people to fall asleep and then fall off their motorbikes. Contrary to your suggestion, I will not need any bungee cords.

The freedom from all the riding I've been doing in the past few weeks is irrational. Necessary. I guess I always knew that hurling myself quickly through the world was the only way to make sense of it.

Don't worry, I'm being safe. And keeping myself in balance. Still.

Your adoring daughter,

Imogen
