Jebus, my arm hurts. I think I overdid Oxford Street. I didn't buy much, but having to carry "not much" for 8 hours can make anyone strain their right arm, I guess. Like an idiot, I didn't pack any aspirin and the hostel staff aren't allowed to administer any sort of medicine for liability reasons, so I'll just have to bear it and drink lots of coffee to get me through tomorrow. (I haven't been able to sleep all night because of the pain, which is why I'm blogging right now. It's currently 6:26 am London time.)
Plan for the rest of the day: Watch changing of the guard. Return impulsive purchases. Tower of London. Maybe pop by St. Paul's and Westminster Abbey if I have time. Oh, and lots of coffee...I'm going to need it after a night of no sleep.
