Isaac Joshua Corbett is 16 years old!

My son, my first born, my baby is 16 years old today!

I'm not old enough to have a 16 year old son...I don't look a day over 25 and am only actually a few days over 35; so explain to me how I became old enough to have a 16 year old son?! I, myself, was just 16 years old last week. And he was just born on Monday.

Is it possible that I'm in denial?
