Let me introduce you to Jonathan. He's my oldest son, and seven and a half years old.
He loves Harry Potter, Beyblade, and reading.
He gives me a manicure every saturday, complete with nail varnish and a hand massage, and stays after dinner to sit and chat for a bit. He asks me how my day was when I get home, and teaches his brothers to read.
He's the best oldest child in the history of oldest children, I kid you not.
