One day I was over at a buddy's place (on-duty, in uniform) watching baseball during my lunch break and some read-headed guy with a beard was on the screen. His young daughter (about 8 years old) looked at him and turned and said, "I can tell, that guy right there is Irish!" I laughed and said, "He is?" She replied, "Yeah, I can just tell by looking at him and it's not just the red hair either." I asked, "Okay, then what am I?" She walked around me pausing briefly and chirped, "Scottish!" I asked, "Are you sure?" She said, "Yup! ...well are you?" I said "Yup." She was taken aback and said, "Really, do you ever wear a kilt?" I replied, "Sure I do." She took on a really serious look and said, "Really?" I said, "Yes, I do." She said, "Next time you wear a kilt, I want to see it!" I said, "Okay." She paused and without missing a beat, she asked, "Um, you don't look like a clown in it, do you?" I repled, "Well, you'll have to tell me when you see it."

I had never given it much thought, but after an exchange like that with a 5th grader, I'm pretty confident most 8 year olds can grasp the concept!
