We were working on Hannah's 'Secret File' (more on that in another post) and she asked what my full name was. I told her and she said, referring to my last name (which is different than hers), "Now that's your sperm name, right?"
"Um, what's a sperm name?"
"It's the name you get from your father. He's the one with the sperm."
Oh dear. Reproduction lessons (goat reproduction, if you must know, though the tie-back to humans isn't that hard for a little mind) are coming back to bite me.
