This morning BlueEyes found an old conference name badge laying around the house and asked me what it was.
"It's a name badge that you wear when you go to a meeting."
"What's a meeting?"
"It's where many scientists come together to talk about science and show each other their data."
"Oh data. So it's like a lab meeting?"
"Yes, kind of like a really big lab meeting".
I guess he hears and remembers all the things that we say to each other. Good to know.
