Tonight at bedtime:
I read Helen a story. I told her it was time for bed.
Helen: “Daddy, now can I read you the story?”
Me: “No kiddo, not tonight. You got one story; you can read me a story tomorrow night, OK?”
Helen: “OK. Can you stay with me? Do you want to have a sleepover?”
Me: “Not tonight, kiddo. Maybe some other night, like this weekend, OK?”
Helen: “You loser. I’m going to cut your head off.”
