My father had one of those light bulb moments today.

He took me to lunch at one of his favorite places. Since I had never been there before, I asked what was good. As he named off several choices, he noticed that I was looking at the Senior Citizen's Menu.

"You aren't 55, are you?" he asked.

As I told him that I was over 55, I realized that for the first time it had dawned on my father that he had a senior citizen for a son and that he might be getting old - like being 86 wasn't a big enough hint.

I thought about rubbing it in a little, but I didn't. I let him deal with it in his own way.

After lunch we got back in his truck and he drove us back home.

You see, for all the milestones we pass in this life, you are really only as old as you feel, and I have a father who has no idea how old he is.
