I was scared of committing, really committing, to this relationship. And I missed Mom, Dad and Rory as achingly as ever. For so many years, Thanksgiving had been something to brave — every year another mark on the wall. But this Thanksgiving, here with Caitlin, wasn’t just one more to endure. History tells us the Plymouth settlers, when sure of a good harvest (and good defenses), repaid their native hosts with mistrust, disease and war. It’s hard to survive, even harder to stop behaving like a survivor.
