No talking during lunch. This was in a public elementary school in the early/mid 90s, at the first school I attended through second grade. Literally the only school I attended that was like that. It was so fucking stupid.
Of course, kids tried to talk to their friends, whispering and such. I got in trouble once because a teacher saw me whisper to my friend who asked me a question and so I got moved to sitting with older kids I didn’t know for the rest of the lunch period. That was the first time I got in trouble at school, so I was crying.
Never understood why we couldn’t talk. I think because it’d eventually get too loud in there? Which, who cares? Didn’t matter; family moved and I switched schools. Where it was totally normal and acceptable to socialize during lunch.
