Do a good deed for someone in need.
If you see a fellow human being struggling to cross the street or to climb up the steps, offer to give him/her a hand. When a blind person taps his walking stick, he is alerting the surrounding people, in some cases YOU that he/she needs to hold on to you. Please be alert and offer some help. I can’t count the number of times I would see this happening to no avail.
