It is becoming a very sad world. I have by choice withdrawn from it, but do have to drive into towns and cities for various reasons...it really saddens me when as with your example, I come across people struggling, or the elderly making mistakes. I don't have to think twice to help, and the bystanders? Some of them were just taking photos or videoing, I guess to send to their friends or Facebook.
What is wrong with people?
I think 'what is wrong woth people' is an eternal question.
