What's with the dirt???

As you know Dave comes from a Hispanic back ground. On one occasion Samantha brought up an interesting question for her Dad. She was around the age of 2 years old. Dave had come home from work and he washed up for dinner. Samantha had a questionable look on her face. She asked her Dad why he had not washed all the dirty off of him. He said...that he had. She replied....no, there was still dirt on him. He said, no there isn't. Samantha started to rub his arm very roughly, saying "all this dirt" why won't it come off. Dave and I looked at each other and started to laugh. We had to explain to her that Dave's skin was darker then hers. We put our arms side by side...to show her how each of us had different skin tones. I wonder how long she had ponder this in her little mind. She now tell me at the age of 25 that she did wonder as a child why he went in to take a shower but, still came out looking the same.....with dirt still all over him.
