I don't want to help a classmate that it throwing up.
Oh no. Truly think you are joking, please say you are. I don't understand. Why wouldn't you help them?
Because they clearly came to school sick!
If someone is vomiting in class then you shouldn't always be the one to help them. A nurse or a teacher should help the student instead.
The nurse wasn't there, and the teacher just moved the kid to a corner and didn't say a word. I think the teacher is in on it.
Well, then you should help the kid. Someone should call the nurse right now so she can be there. Why would a teacher be in on making people sick?
