Spent the day today in an elementary school gymnasium, from 930 AM-330 PM. My daughter was playing in a chess tournament, and rather than giving the parents and coach a classroom for waiting and coaching between rounds, as most schools do, this school decided that everyone could just wait in the gym.
No chairs (well, they rounded up a few plastic ones), and literally a hundred or so (but it seemed like 6,565) screaming, running, elementary school chess players.
They sit quietly and concentrate during the games (in another room), but between games, they have to run, scream, wrestle, squeal, chatter, whine, fall, jump, and create agony in any adult in the region.
