Above: Traffic - outside the Kathmandu Valley, approaching Mugling Bazaar.
A nice bit of road, gently sloping in the downward direction and some truck action. Despite the seeming congestion, nothing to worry about at all - everybody's quite well behaved and following the rules.
Mr P is, however, about to get an air-horn up his bike pants for his troubles, but it won't be the first time. Heh! Heh! You gotta laugh...!
I probably could have warned him about the oncoming bus, but this kind of prank comes under the heading of Bike Humour, which is well within the rules.
I will admit that Bike humour can appear, to the outside observer, as infantile at times, but when you're out there on the road, dancing with death, oxygen surging through your brain corpuscles, humour rapidly plunges from the sophisticated urbane (you're used to at home) to the slapstick rural, and you may never have laughed so much in your life.
In fact, you can live off this kind of prank for a couple of days...
