This is how I know, that the twelve year old boy Noah, who lives in my house, is actually my brother and not a baby my parents found in the mountains being raised by wolves.

He comes home from an orthodontist appointment at 8:45am and says to my sisters, let's make mac 'n cheese. And they are saying, Noah, it is nine o clock in the morning, but I almost say, if you make some mac 'n cheese I will eat it.

That, and the fact that I was around when he was born.
