(Scene: riding along in the car, The Grateful Dead's Touch of Grey comes on the radio.)
Me: Now, this is a band you need to get to know at some point. Something to keep in mind for someday. This was their only real radio hit, and not the best song, but its a good start.
Him: Um, if this is their only radio hit why are they so awesome?
Me: Because the radio isn't an indicator of good music. Its simply an indicator of what other people think is good music.
Me: Anyway, they were a great band, and they had thousands of concerts for twenty some-odd years and some people spent their lives following them around going to all their concerts. They recorded live shows and sold tapes and it was a really grassroots thing, how their music became part of popular culture. And people just loved them, and their music, and they danced...and they did a lot of drugs.
Him: ...wait, what?
Me: Like, A LOT of drugs. Some of those people can't eat soup off a spoon now, they did so many drugs and it killed too many brain cells, but hey, the music was good.
Me: So if anyone ever tries to get you to do drugs, just remember, you want to be able to eat soup off a spoon when you get old.
Him: Mom, I'm not going to do drugs. But that won't be the reason why.
Me: I don't care why, as long as you don't. That's as good a reason as any. Besides, when you're in that situation, and you will be, and someone is trying to get you to do something you don't want to do, sometimes it helps to have a funny reason to stand your ground. It diffuses the stress of the situation for you.
Him: This song is kind of lame, mom.
