In Calgary

I'm waiting for my flight in the Calgary Airport. Specifically, I'm sitting in the Tim Horton's at YYC, which seems like an incredibly apropos location for my final few hours in Canada. In two hours, I'll be flying into London (the big one, not the little one), where I'll spend a couple days before boarding a plane to Accra. I have this nagging feeling that I have forgotten something, but I'm hoping that's just normal.
