Sometimes trying to explain things to a young child in an age-appropriate way can leave them more confused.
Other times, it leaves them expressing a truth that you never thought someone so young could know.
Yesterday in the car, we heard one of those "Christmas greetings from deployed soldiers" that the stations play between songs. When it was over, the announcer said, "That was a Christmas Greeting from one of America's heroes."
Little Brother said, "Why are they heroes?"
I told him, "They are protecting our country so we can have freedom."
He considered this for a minute and then said, "I thought GOD does that."
