Our hands are still clasped, but I hook our pinkies. Leaning closer to her, I say, “Kiss your thumb the same time as me. Yeah?” Her lips twitch into a tiny smile, and together, with locked pinkies, we kiss our own thumbs. When I let go, she whispers, “That’s a very earthly promise.” I start to grin. “That’s ‘cause I’m from Earth, space babe.”
