DS17 really wants to go. Last summer he went to another festival, we found out afterwards he had taken MDMA, Ket & smoked weed. He lied until we showed him the evidence.
He's been really well behaved since then, I am thinking he should be allowed to go on condition that he continues to behave well & gets good results in his summer exams.
DH is very conflicted. Thoughts please, preferably from parents who have direct experience of dealing with these issues.
