The afternoon sun was sitting low over the cedar fence in Jason’s backyard, turning the heat from the grill into something heavy and thick that stuck to the back of my neck. I remember watching the grease drip from the tongs onto the hot coals, sending up little puffs of white smoke that smelled like lighter fluid and burnt sage. Chloe had just set down a pitcher of cloudy lemonade on the picnic table, the condensation running down the glass and pooling into small, dark rings on the weathered pine boards. It was supposed to be a simple family birthday gathering for the twins, just the sort of Sunday afternoon where everyone pretends to get along because there are burgers on the plates and nowhere else to be until the sun goes down. But then Jason stood up, tapping his metal fork against the side of his glass twice with a sharp, pinging sound that made the kids stop wrestling by the garden hose. He cleared his throat with that particular dry rattle he gets when he is about to announce something he thinks makes him look clever, and I felt a cold little knot tighten right under my ribs.
