Portrait of a something as a young someone

I'm gonna guess that this picture was taken on Christmas Eve when I was about three. We exchanged gifts on Christmas Eve; it made it difficult to get into the whole Santa Claus thing, but I was otherwise quite well immersed into the rest of the American culture.

This picture was taken in Westminster. We lived in the garage while my father was building the house. As you can see, well, you can see.
My father's mother, Mummu, is on the right.
