Dear Eric: He’s gotten great work, won awards and become relatively famous. We’re so happy for him and remain close. He still uses the guest house when he’s in town. In our success fantasies for him, we never expected him to thank us from the awards stage or invite us to meet his new, famous friends. But the dynamics of our relationship have not changed at all. He still has never picked up a check or even offered to pay his share. If he needs something in the guest house, he asks us to buy it on our next grocery trip.
