Dan Hoyle's performance class

I'm doing it this time around. From what I'm writing:

I move to kiss Baz goodbye, but he’s already gone and following instructions. “Well,” I say, “I’m going to slip out before he gets back.” She smiles in response, but there is no need for me to hide my departure. He loves it here. He doesn’t care that I’m leaving. He’s never had separation anxiety. If that’s such a good thing, why does it hurt so much?
