That's funny. I have been frequently surprised, amazed and frightened by what comes out of my kids' mouths, usually when I least expect it.
I'm glad you had a great trip. I like to ask my kids, after the fact, what the remember about certain trips. Their perspective is very interesting and what I think is the most important thing is usually not what they remember. They have a unique perspective.
One of my favorite questions for the kids is "What was your favorite thing about today?" Even on a normal day..Their responses are always fun :)
