Tea time was generally 4:00 PM. We would all assemble in the dining tent and be served tea or hot chocolate and a plate of cookies and/or Ritz crackers. Most of us would drop in for tea: it was an opportunity to share news, go over the events of the day, and plan for the next day.
Dinner was served at 5:00 or 5:30, so there was a gap between tea and dinner. Usually it was getting pretty cold, and most people retreated to the only other space they had: their tent. I would sometimes find a seat in a nearby dining room, where it might or might not be heated, but where I could sit and write.
