Did I mention that there was a lot of cider? There was also a lot of stupid conversation, a fair bit of serious conversation, and some that could reasonably be placed in either category. One or two people may have had a bit too much of one or more of these things.
My last train home disappeared into the æther while all this too-much-ness was going on, and I ended up staying the night -- curled up on some cushions half-way up the stairs. I got to "bed" very late, about 5am, and was up again around 9am, for a train out of East Croydon at 10:10 followed by a frustrating 55-minute wait for a connection at Clapham Junction, thanks to the poor provision of trains on my home line on Sunday mornings, and I got home at about 12:30.
