I am not saying that children should stop learning stuff outside of school (although some days, when I see how overscheduled some children are, that’s precisely what I want to say). We just need to sign them up for classes that make more sense, given that it’s 2013, not 1860, and that I don’t need a violin-playing daughter to cement my class status. Look, I love the Mendelssohn Violin Concerto, but one could make the argument that Rebekah would be better off learning to play the Lumineers’ “Ho Hey” on guitar. That skill would certainly be more of an asset at summer camp.We can probably all agree that it’s worthwhile for children (as well as their parents) to try new activities, and that there is virtue in mastering difficult disciplines. So what challenges should we be tackling, if not ballet and classical music? How about auto repair? At least one Oppenheimer should be able to change the oil, and it isn’t me. It may as well be one of my daughters. Sewing would be good. And if it has to be an instrument, I’d say bass or guitar. The adults I know who can play guitar can actually be seen playing their guitars. And as any rock guitarist will tell you, there is a shortage of bassists.
