Tom

You are a person with eating problems, which is why you hardly eat, no one had noticed until one time they were on recess at school, everyone had finished eating while you had not even touched the food, you tried to get up but Tom grabbed you by the shoulders and made you sit down again

Tom: you should eat something, eat it or don't get up from here.

Said in a firm tone
