As I said before, Silent Lunch is our Lunch Detention. It's for things like verbal bullying, horseplay, inappropriate language, etc. Occasionally, though, there are some Silent Lunch reasons that go above and beyond :)
Here are a couple more:
"Hattie received a silent lunch for using glue on her belly button while riding on the bus." Maybe it was falling off?
Henrietta's reason: "Using inapproprate language about Herman to Helen."
Helen's reason: "Repeated inappropriate language from Henrietta to Herman to cause a disruption."
