I'm surprised, I figured it would be invite little billy from next door, tell him how talented he is and how lucky he is to live next door to a world famous stand up bass player, and that if his mommy and daddy really loved him they would give buy him music lessons from you. Then you right up a non refundable contract for them to sign.

But first you need to figure out which instrument they hate the most, then go to the pawn shop buy it, never tune it, and teach billy on it, and tell billy he needs to practice at home for 2 hours every evening, and that you would know if he did not because you can hear him from where you live when he plays.

Two lessons, three at most and you have been paid for six months worth of lessons, all without crushing a little kids heart because mommy and daddy did that for you. ;-},
