OK - this really is silly. I just heard a car alarm go off, and thinking it was mine I went running out into the street in a quickly pulled together outfit of hoody, tracky pants, and mis-matched shoes.
Apparently it was not my car; some inconsiderate bastard appears to have a very similar alarm, and their car is punishing me too.
And to top it off, two blokes were out in the street changing a tyre on another car (well, I suppose they could've been stealing the tyre...), and I just looked like a nutter who ran out of his house, stared at his car for a bit, then ran back in.
At least if I was wearing Spider-Man jim-jams I could've gone "pwish pwish! Just you're friendly neighbourhood web-slinger!" and left them standing there in absolute awe of me.
