Square Dance!

Dan has some rules about clothing - most specifically - Dan and I can't wear matching clothes (colors) when we are out. If we both have on, say, the same color of green shirt - Dan will say "We are not going to a square dance!" and one of us will have to change into a different color.
It seems, as shown below, that Dan and Phin can be matchy matchy and it's just cute father - son stuff!
