There has always been something about this photo that has bothered me. I think it's the expressions on the girls' faces. It's not the suspicious unsmiling expressions on the girls, primarily. It's the fact that the boy's expression is well, expressionless. Why?
When my son was that age he would have been wearing the same expression as the girls. He didn't like having his picture taken and would have been grouchy about it. He was being forced to do something he didn't want to do, which is what the girls expressions tell me.
So the girls seem like normal kids, to me. It's Francisco. What was he thinking?
