(This happened about 10 days ago, but it is worth repeating)
We were walking down the main North-South street in Dushanbe in the middle afternoon. The street is broad and treelined and has a nice smooth sidewalk on both sides. There are lots of pedestrians.
Suddenly we heard a scream and turned to see a lady's head and shoulders sticking out from the ground. She had stepped on a loose manhole cover, which had pivoted and dropped her into the ground.
The moment was so slapstick that we didn't know whether to laugh or be horrified. Fortunately she was OK, but both Lara and I step carefully over manholes now.
