Wenner began a campaign to get his parents back together. Sim told her son she wanted him to call only every other week to reduce her phone bills. “Your demand that Dad and I be something to each other that we’re not, is basically a child’s demand,†she wrote to him in 1959, when Wenner was thirteen. “One stamps one’s foot and says, ‘Change the world and I will be all right!’ and it’s a nice comforting thought to have, but the world can’t be changed, families can’t be changed, mothers, fathers, sisters, brothers…There is only one thing that can be changed, or rather, only one thing that you can change, and that is yourself.†(“Maternally yours,†she signed the letter.)
