Sometimes, especially while on the bus, thoughts simply pop into my head, and then I extrapolate long threads of thought and association out of them, and when I get home, I forget all about them, no matter how interesting they were. Here's one I got while on the way from the bus station to home: a system for classifying rain. This should be two-dimensional at least, because there are two main criteria for judging rain as I experience it: the size of the drops and their frequency. Other criteria are of less or no significance to the way people feel when being rained on: the amount of sulphuric acid, say, or the water's hardness.

Another thought about rain is that actually it has to fall quite a long way (except with very low clouds; I have at times seen small clouds lower than thirty meters above the ground, and that not only on top of mountains) before it reaches the ground; and that clouds can be very fast, so that when it starts to rain where you are, the rain reaches the ground at least a few hundred meters away, and when you get wet, the rain started falling not only far above, but also to the left. And even when the clouds are almost stationary, there will be a delay between when it starts/stops to rain and when you notice.

Lastly, an interesting coincidence. In a town in Bavaria where my family have been three times so far (on holiday), there's a certain café where the same thing has happened to us one time in each holiday: it started to rain very heavily exactly when this café was the closest point where we could shelter.
