Ah the pleasure of the slow stopper:
How one relaxes into the solitude…
Much later, and across the Severn by road, Wales began (as usual) to rain.
A black carpet gives you warning, and blocked plumbing realises your worst fears. One of the nearest-and-dearests reconstituted himself as the Human Plunger and, with a technique never matched except in the most dramatic fake CPR seen in medical soaps, dislodged the sludge. (My hero.) This left us with the problem of walking without touching the carpet (fairly easy) and of sleeping without touching the sheets (fairly difficult).
The event itself involved the usual scrum, with an excellent mitigation: an official quiet room. Here I joined the autistic-spectrum mates and rellies and ate my plate of buffet in peace.
