I saw an elderly man leaving a supermarket barged out of the way by some over enthusiastic teenagers who didn't give him a second thought as they ran into the store. He shakily sat down on a nearby bench clutching his trolley to get his breath back. I asked if he was ok? He nodded sadly. I told him that the last time I was barged out of the way it saved my life. We ended up having an amazing chat about the unknown people who save lives (rather than the idiots that end them). I'm sure many people have been saved by strangers they wish they could thank; and would be grateful to hear of any experiences that I could relate back to so many people that are giving up on any humanity left.
