The following thread viewtopic.php?f=7&t=505 reminded me of something from two weeks ago.
I was driving on a fast lane (southbound Papineau, north of the 40 - for those familiar with Montreal). At a light I noticed something in my rearview mirror: the taxi driver behind me was pinching the chick of the person next to him and shaking his head. I quickly realized that this must be an authorized taxi for handicapped people. I kept looking and the taxi driver was saying something to his passenger but also he was sometimes slightly slapping his on the cheek.
The passenger didn't seem to enjoy the treatment. I felt my adrenaline level increase as I considered stopping the car and facing the driver behind me or calling the police. However, I decided to keep watching to see what was going on. After a while, I did not feel so sure that I should stop. The scene seemed less offensive than at first sight. It looked like the driver was explaining something to his passenger or trying to encourage him to do something in a rough manner. I am not sure that it was abuse and since the scene was just below some unconscious limit that I have for witnessing abuse, I decided that doing something rash may make things worse: get a person accused of something he may not have done based on circumstantial evidence.
I made a mental note of this and left but I kept pondering when would I intervene if I witness something? As most of us know, situations are rarely black and white, so there is a lot of confusion as to what goes on. Also, my personality dictates me to wait and appraise a situation before being sure that I REALLY need to step in.
