I'm in a cafe. There's a quirkily attractive man at next table. I apologise in advance for DD's noise disturbing his reading. He smiles and we have a short chat about kids. I ask if he has any. He replies
"No kids yet, they're all in protein form."
I assumed that he meant sperm. I think he was trying to be funny, not gross. I wish I'd had a chance to ask.
What do you think he meant?
