Some of the funniest things I hear from my kids or hear myself saying are the unexpected ones, like:
"You're not allowed to put drinks in your back-pack."
Bernie to me:
"Mommy, can you sing the Soprano part for My Country 'Tis of Thee? The only part I can do by myself is the Bass."
UPDATE: Okay, I remembered more.
The other night, Frank, Gus, Ria and I were having a late night discussion about the meaning of the word "important". (Frank particularly likes late night discussions.). When that one ended, Frank very politely asked:
"Is it too late to ask about how airplanes fly?"
One day Kate came up to me and explained:
"I was just sitting on my bed and telling myself about all the nice things I'll do when I go to heaven."
