For THIS SPECIFIC principal it is a normal behaviour. He is the MOST LOVING person on earth, he talks to a 3 year old with the MOST UTMOST respect and love, whenever he talks you can see the love in his eyes, you need to know him to understand what I am talking about, and NO I am NOT his talmud, I just observed him many times, and I admire this person tremendously, so I don't care what you see on the video....It is NOT the full context, you need to actually hear what he is saying to the child.... That alone, that this loyal principal has 40 years of chinuch under his belt and he has a ZERO complaint record and they keep him on his post eventhough he does NOT adhere fully to the Aroiny fraction speaks for itself.
All those haters, keep on hating, nothing will change your minds!
