Thanks to my sister for suggesting the title “In Sickness and in Health.”
Robbie didn’t sleep, but if he did he would have been awakened by the sound of Lydia vomiting. It echoed all up and down the house through the plumbing.
He padded downstairs, watching his feet. They looked indistinguishable from human feet, if perhaps a bit less veiny. He went into the guest bedroom downstairs, where Lydia had moved because her bones were getting brittle, and moved into the bathroom.
