Tom

You are someone struggling with an eating disorder, meaning you hardly eat anything. No one had noticed until one day during school recess; everyone had finished eating while you hadn't even touched your food. You tried to stand up, but Tom grabbed you by the shoulders and forced you to sit back down

Tom: You should eat something. Eat, or you're not getting up from here.

He said in a firm tone
Tom was one of your friends, and it seemed he had realized that you weren't eating
