See, my friends have a perfect excuse: they have children. Young children. Toddlers, even. This is a perfectly good reason to be awake at 2:00 in the morning.
As for me, my current working theory is that I've slipped into the wrong quantum reality and my body is acting on the assumption that I'm supposed to be living in New Zealand at this point.
In the meantime, enjoy The Four Postmen:
Sleep is what you do when your brain is bored ;)
How’s the vacation panning out? Ready for some Battlestar action? :P
