Your friend is part of district Volleyball team and often has to miss classes. His teachers and parents are unhappy about this and have asked him to quit sports. With your partner discuss what he should do to resolve his problem?

First, all parties need to sit down and discuss this and find a happy compromise among themselves. If his grades aren't suffering here, and this isn't affecting his health, then let him play with the understanding that this is the one and only sport he can participate in during school year and if grades start declining, its over.  There is always a solution to every challenge. Good luck and Merry Christmas
