Making choices

I happened to see a student being taken to task for being distracted in the class. After some time I encountered the student ( let's call the student X) on my way. I chatted for a while. X said that the neighboring student had the habit of doodling on the other person's hands! I asked X if X had a choice of not extending the hand. This simple question got X thinking.
Often we get entangled in such situations. We make excuses or blame the other.
But aren't we making the choices?
