A man was sitting in a meeting with many people. He knew some of them but not everyone. We could go into any group of people anywhere in the world, and go through this list, and everyone would see himself or herself. One of the basic human experiences is not being accepted, not feeling included, or feeling that we never measure up. Middle age people feel the pain of rejection.
Elderly people can feel the pain of rejection.
The elderly can be abandoned by their children, left alone, and ignored by all the people around them. Just about everyone experiences the horrible pain of rejection. Everyone feels different because everyone is different. No one is ever really included. No one is ever really accepted in life.
