73: fun mileage

Today I looked down at my odometer and my mileage was 123456.
That's the kind of thing my dad loves. I forget what the mileage was, but we were all going to North Haven and my dad was hanging over my mother, totally in her way as she was driving on the highway, trying to watch the mileage change. It's always been a big deal with him when the number line up, like mine did, or when they are all the same: 44,444.
So I gave him a call and told him. He completely didn't get it. My mother was in the background saying "her mileage. On her car. It's 1-2-3-4-5-6." Nothing. Oh well.
The question is, do I keep trying? Do I tell him things hoping he'll get them and get a kick out of them? It's just so damn sad.
I answer all kinds of questions on Yahoo Answers about Alzheimer's and some of them make me cry. I am such a softie crybaby wimp sometimes.
