a gangster-like man almost collided into me. I am an agile guy , I was able to dodge to avoid the collision. I didn't get angry, because I understand that that gangster-like man needed to prove if he was able to scare others by an experiment. Of course, this gangster might think I had to give him the way because he is a gangster. What if I didn't do so and he crashed into me, then, fell down on the floor? Should I grasp his hand to assist him standing up? He may have an insulted feeling.
