Recently I was walking through a zoo, and stopped for some lunch with my family. Out the corner of my eye I saw a family of four. The mother was attempting to take a photo afar of her two kids and Husband on the step of a fountain. She shouted for them to smile while the Father had his arms wrapped around them . Nothing unusual so far right? The Father then stepped down off the fountain to look at these photos she had taken on her phone, and appeared to nod disapprovingly at them. He then returned to the same step, asked the kids to smile again while all three of them adopted the same pose. Again he came down, didn't approve of them and returned to get another photo. This cycle continued for several minutes. The children were clearly becoming less and less interested in having their photo taken, their smiles became less disingenuous and by the end of it both parents were shouting for them to smile on command. Eventually another family gate crashed what was going on before they decided to move on.
