Brief observation, query

I have been living alone for about eight hours and already I am talking to myself like a loon.

In other news, if anyone has an idea for a reasonably straightforward Android app I could make then I'd be interested to hear it. It doesn't need to be useful for more than 2 or 3 people in the whole world. I used to have a database set up to produce the most efficient route round the UL from a given set of classmarks, so maybe I could try to do that, though it wouldn't be much use to me these days. Or I did wonder about an app for making a brief note whenever I see tube mice. Tube mice make me happy.
