I would write more, but I'm not going to right now. Suffice to say that my mother and I have made it to London (and to our hotel!) and are both struggling to stay awake until some reasonable (or even only vaguely reasonable) hour to go to sleep. As it is now nearly 2pm, we're going to have to struggle vainly forward for the next four hours or so.
See, I shouldn't write when I haven't really slept in three days. (or whatever.) I write things like "struggle vainly forward" and all I'm talking about is sleep! That is hardly that dramatic. Oi.
Also, I made friends with a street cleaner.
