pre-teens and teens ages 12-18 what is your bedtime?

Mom says going into 9th grade does not mean I need any less sleep. Bed time t on school nights remains at lights out by 9.30. Rest of the time bed times are less rigid. But when dad says time for bed Ricky it is best to go. Unless you want to go ten minutes later with a red hot tail. I found that out the hard way
