STEVE and I are chatting away about something in the front seats of the car. In the back seat, JANE is looking out the window or something, keeping her own counsel. ABRUPTLY:
JANE: Ice. Burn.
ME: Ohhh, ice burn.*
STEVE: "Ice burn!" is what you say when someone says something mean but funny about you.
ME: Mean and funny and true!
JANE: Yes. Ice burn. When you have ice sometimes they burn.
US: Uh huhhh?
JANE: And then you can't see. Ice burn!
STEVE (light dawns): Oh! Like when you cut up onions? Because you're crying?
JANE (contentedly): Ice burn.
*This is, in fact, something we say around the house.
