Let's see: 62 + 18 = 80. When this baby reaches 18, his mama will be 80. Somehow I just don't relish the idea of dealing with a teenager when I'm 80.
That's what older siblings are for. My mother in law is the youngest of a fairly large family. She was an aunt several times over when she was born. Her older sister more or less raised her, although her mother was still alive when I first started dating my wife. About 90 at a time when MIL would have been about 39 or 40. (Now that's a scary thought, my wife is now 16 years older than her mother was when I first met her.)
A 17 year old kid I knew at Christian camp years ago had a father who was 72. He felt more like his 40 year old brother was his father and his dad was more like a grandfather. Interesting.
