Daughter Cori has always been able to make me guffaw in surprised laughter. Her timing and phrasing is guaranteed to unspool me. Here's an example.
Last night, for whatever reason, i was pondering the odd parental promise of "I'll give you something to cry about!"
Without any hesitation Cori said in her deadpan way, "I'll give you something to cry about--there's no Santa, and your grandma isn't in heaven, she was a bad, bad person."
i became helpless. (Also a little fearful for any future children.)
