For 3 days starting today, my whole class is going to trips for 3 days. We just went to our first trip and on the way back, i threw up. My teacher took me to the office and i told told the vice principal what happened. (The trip's cost was $26) She called my mom and said that i cant com on the next 2 trips because she is worried that i might vomit again and ruin the bus. My mom asked if we can get a refund and if i can just stay home for the 2 trips. The principal said that there are no refunds. Also she said that if i dont cure my motion sickness i cant come. But if i dont go, it will be a waste of $26. Please help!! Alwo, im only 11 years old and i cant go and buy medicine or drugs or anything.
