Reminds me of being in a tightly sealed college classroom in the winter with the heat on, surrounded by...uh, foreign students. OH MY GOD ! ! ! ! ! ! !
Actually, back when I was teaching HS warm spring days could really bring on eau de teenager. Many of them did not use deodorant. They made us stop burning candles (fire hazard) and sometimes it got pretty ripe. We were not allowed to open the door (post Columbine Safety) nor windows. The kids would complain, but there wasn’t much I could do.
