I was caught off guard, and almost caught.
While organizing pics by theme (holidays, vacation, school pics, etc) I came across 2 Santa pictures (one from 2008 and the other from 2009) with my youngest son, Christopher, sitting on Santa's lap. He wanted to see and so I showed him, and he asks, "Why does Santa look so much younger in this pic?"
I was usure how to answer and responded with, "Good question. Go ask Dad."
And then his dad said, "Yeah, Santa looks different every time I see him, too. When I was a kid he was Black."
Christopher said, "That's weird."
