If one finds himself driven to his or her breaking point by pranksters, he or she should realize that it is a losing proposition to react either negatively or positively. If one reacts even if he or she knows the prankster has no basis for his allegations, then one becomes unreasonable. If you react positively, the prankster may think you are enjoying the exercise, and a repeat would be most likely. In both instances, the person who is the subject of the pranks, is in the losing end.
So its better not to react.
