Aharon cast his staff before Pharaoh and before his servants, and it became a serpent. Pharaoh too summoned the wise men and the magicians; and the necromancers of Egypt did likewise with their (lahat) magic. (Shemot 7:10-11)
A substitute maths teacher had been teaching advanced maths to the class for over two months. The class responded very well to her methods. One lunch break she met another teacher in the staff room, who told her, “You have a tough group there. I hope they are not giving you too much trouble”. The substitute teacher responded, “What could be wrong? I have the A group”. The other teacher then said, “They forgot to tell you they switched you to the C group this time!” The C group were much more capable than anyone had thought. It took an uninformed substitute teacher to bring their talents out. Sometimes in life the labels we ascribe to others limit our expectations of them and their perceived capabilities. Avoiding those labels in the first place could prevent us from capping our potential achievements.
