Writing the post, he said: "A six foot five man suffering from drug abuse and\or mental health issues was being very aggressive on the bus with erratic movements, cursing, shouting, etc.
"While everyone was scared, this one seventy year old woman reached out her hand, tightly gripping his hand until he calmed down, sat down silently, with eventual tears in his eyes.
"I spoke to the woman after this incident and she simply said, 'I'm a mother and he needed someone to touch.' And she started to cry. Don't fear or judge the stranger on the bus: life does not provide equal welfare for all its residents."
"It was the most touching thing I've ever seen.
"She was very brave," Taha added. "She even mentioned that she thought about what would happen if he stabbed her with the pen - because he had one in his hand -- but she said it was more important he didn't feel alone."
