So when Lukasz pointed out himself on the tv while I made dinner, I waited for Lily to correct him and tried to figure out how to tell her that what he was saying was fine and to somehow get her not to correct him... he's at a stage where the slightest discouragement can snowball.
I heard the following exchange:
Lukasz: "That's me!"
Lily: "The astronaut?"
Very noncommittal and she left it at that. Whew. :)
