There are such over-the-top fantastic folks.

There is a store down the street that's a bit far for my old knees so I roll there in a chair. The store does not have automatic doors.

The last time I went there, there wes a group of young men hanging out nearby. One of them saw me coming and nudged another, nodding in my direction. The one nudged rushed over and opened the door for me, then followed me in. After I took my time shopping and had paid and was headed for the door, the young man magically appeared from behind me. He had hung out inside in order to open the door again. Furthermore, he opened the enter door for me to exit by, realizing that it would be easier for me to navigate than the exit. I was VERY touched. Folks like this add a great deal of enjoyment to old age.

If that's any indication, the world will be in good hands.
