My sister kissed my husband in front of thirty people at her own anniversary party and called it a joke. Her husband had a wrapped present in his hands and an envelope she had never opened.

“If I’d met you first,” she said, “I’d have picked differently.”

I had a mouthful of water and nearly choked.

Bram went scarlet.

Callan laughed.

I looked at him.

I waited.

I wanted him to say something that made it clear there was a line.

Instead, he smiled into his glass.

“Sasha,” I said quietly.

She turned toward me.

“What?”

“Don’t.”

She laughed.

“Oh, relax. You know I’m joking.”

But she wasn’t joking.

Not really.

She spent the entire evening at his elbow.

She asked him questions she could have asked me.

She touched his arm when she laughed.
