This has happened several times with me.! One of my kind was when i was in the annoying bank queue line, and some one come in from no where to join the line in the middle. No one was ready to give him space to join the line so they he decided to ask one by one. I noticed he was uncomfortable so i tried to look around and outside the bank through the glass and saw that there was one of his colleague who was waiting outside and was abnormal/disabled. So without thinking i just gave him my position in the line and i went back till the end of the line. That was one of the kindness and he was so happy and he said "God Bless You"
