That's all I needed. One of the neighbour's children has somehow acquired a vuvuzela doodad and has begun honking it this evening. Here's hoping the little honker makes himself go deaf, or blind, or away somewhere.
I had a brainwave about these vuvuzela thingies. What FIFA should do is arrange for some different ones to be made, which play different notes, and which people can exchange for their existing ones for free. If they were to make them so that they played the notes of, say, C, E and G, then at least we'd get a nice triad type chord instead of the monotonous B flat drone currently being produced. And you never know, you might even get some random tunes generated.
