I'm going to go to school instead of staying home while contagious
Why would you go to school if you are sick and contagious?
Because my parents are too strict about my health
It's understandable that your parents want you to keep up with your education, but it's not right to jeopardize the rest of the students and teachers. It can be a really serious disease.
I can't see what's so wrong about this. I need to keep up with my attendance and I'm not too sick. Everyone is going to be fine if I keep my distance.
Well putting others at risk because of your parents is not fair to the kids at school. Try to understand that it is more morally right to stay home when sick so you do not spread your sickness to other people.
