Conversation with 6-year-old Ariana last week on our way home from school . . .
Ariana: “Mom, do you know what ‘photo spores’ are?”

Lori: “Uh . . . no.”

Ariana: “I’ll give you a clue: They are responsible for an organism’s bioluminescence.  Do you know what ‘bioluminescence’ is?”

Mom: “Uh . . . no.”

Ariana: <patient sigh!> “I’ll give you an example: Jellyfish are bioluminescent because they have photo spores.  It’s kind of like glowing in the dark.”

And I thought that parents only become “dumb” during their children’s teenage years.
