Tiny caterpillar

What a run of blips, fish, a rabbit, a bird, now an insect. Actually I just questioned myself on this, a caterpillar isn't an insect is it? Even Google isn't clear on that. Anyway, my dad decided he might like it as a pet (it's on his hairy arm not mine). It's only about a cm long. It's living in his garden for now.

I am so excited...three more work days then I'm off for a week. Right now, I'd like to sleep for the 168 hours, but it's unlikely I'd be able to (legally) procure enough medication for that...
