Aren't kids great?
I had just come home from a 1 year deployment and my daughter was 3 or 4 years old. Some kid rode his bike through the yard and I asked her who it was. She say: "Oh, he's one of the D@*#heads." Nice and calm as if she were saying his name was Smith. My FIL had a bad habit of calling the kids he didn't like by that name......
I had to ask him to refrain from calling them that while his grand daughter was present.
