She wants to quit because her Mom is band president or something....probably feels like Mom will find out too much being that closely involved with her school extracurricular activity or something. P.S...consider changing your profile pic please....you're too young to post a pic of yourself like that. There are pervs & trolls here too! : )
I wouldnt quit the band. You should've thought about this before your Mom committed herself to that position! : ). You'd also be letting down your band mates too!
