Goon on ya. But do be careful...
I recall asking my dad about that age about MJ...I recall vividly that he said yep, he used to do it and really enjoyed it. That was better than my mother lying about her history with the plant. But kids are so impressionable and YOU are a hero to your son. Just be careful...that's all.
Sounds great though. I have a son about that age too...the drug subject has come up, but I haven't gone 'there' yet. Goon on you and your son for being brave.
