I'm walking down the street and I see a grandfather of 80 years old, he leans on a cane when he walks and carries a package in his left hand, and there are groceries in it, grandfather reaches the stairs and looks around for people, finding no one, he starts to descend the stairs, I go from behind him and when I pass by him then I hear from behind me: "Oh.. miss.. please help the old man.. I can't see well and I might fall.. ah... oh.." I turn around and see this grandfather
