A friend from Germany commented that back home she would always know what the weather was going to be like for the rest of the day just by looking out of the window, but she had great problems acclimatising to British weather where you can experience all four seasons in one day. Understanding the British weather is simple. First, choose an easily identifiable but distant feature that you can see from your location. Done that? Good. Now, when you want to know what the weather will be for your area, then just look out and check whether you can see your chosen feature. If you cannot see it that means that it is raining; if you can see it, then it is going to rain.
For all that people complain about the rain (and we have raised grumbling about the weather to an art form), one of the consequences of such precipitation, sciatica apart, is, the glory of the countryside, our green and pleasant land.
