At about half past two I was up near the bank when Boingy went over the edge.
Fast. Very fast. Arrived at the bottom in a sitting position with nettles up both arms and no wind left at all.
"Oh no," I said, over the edge, and I meant it.
And then I sat down at the top and kept company from a safe height, which is the only sort of help I had to offer, since I was not going down there.
