Going glastonbury festival with my dad?

ive been leeds fest with my mates loads and really enjoyed it but the parts i enjoyed most were around the tents getting drunk and in the moshpit at prodigy all awesome, so going with my dad will be wierd plus i dont know if i'll enjoy it that much, im gonna be 18 and since its me and him going i feel like id have to stay with him. my mates all have exams then but ive finished mine i doubt i'll be bored cos i'll just be watching gigs with him but then after the bands have finished its just me and my dad at a festival where, lets face it, people just get drunk stoned and ****....shall i go or not?
