And very annoying, coming as it does only a year or so before I get to start making my own schedule and sleeping at the hours I used to prefer because we'll own our own bookstore.

That's still so awesome. And maybe you'll be able to lapse back into old sleeping patterns, once you can. Or maybe you'll be all responsible and get up super early, because it's your business and that's surely got to be more inspiring than getting up to help run someone else's business. :)

(You seriously have to see Black Books, if you haven't yet. Although I don't know if it's available over there. But there's this bit where the bookstore owner doesn't want to wake up early, because "no one wants to buy books at half-ten!", and then the 'I Love Books' man turns up, and... well, it's funny, I swear!)
