Ava: Do we "live on a planet of the sun?" (Direct quote from a Sesame Street song.)
Me: Yes, honey. (Then seizing an educational opportunity, as I so often do...you know, since I am super-mom.) Do you know the name of the planet we live on?
Ava: (Thinking hard.) Texas?
Me: Good guess, honey. There are quite a few Texans who probably believe that. Come to think of it, probably many non-Texans think this must be some other planet as well.
