I

The other day, Cameron and I were driving to school, just the two of us.  "You know what?"  Cameron said from the backseat.  "When I was in preprimary, everyone knew Matthew was my brother.  But in elementary, some of the kids haven't seen Matthew before.  Lots of times, when they do see him, they say, 'Who's that kid?'"
"What do you say to them?" I asked. 

"I say, 'That's my little brother, Matthew.'  And then they usually say, 'How is he your brother?' I think because Matthew's black and I'm white."

"I think you're right," I said.  "Lots of kids aren't used to seeing brothers that have different skin colors.  What do you say when kids say that?"

"Well," said Cameron, "I just tell them!  He's my brother because I adopted him!"
