I think there’s a rule that says 80 percent of all punctures must happen when it’s raining. Actually, there probably is some sort of cause and effect to be argued about the water lifting crap and washing it onto the road to settle in that two feet nearest the kerb that is nominally my domain. Said crap would include glass shards or other debris large enough to get through the tyre wall to the inner tube.

Just to make it worse, I think the replacement inner tube I used might have a slow puncture of its own and I’ll have to go through the whole routine again before I can set off for home this evening.

But I’d still rather do this commute by bike than by bus or car.
