Machine summary:
This Servat School in the Arabs' neighborhood, as I remember, had a large courtyard, but years after graduating from high school, I went to visit it to revive my dear memories and saw what a tiny courtyard it had, and I remembered the words of the late Haj Hossein Mr. Malek, who used to say: I had an aunt who always looked at me as the same child whose milk she had given; when I returned from Hajj, I saw the old woman, with her moist and semi-sighted eyes, had sewn a few pairs of pants for me with her own hands, but they were exactly the size of the pants they sew for infants, and she presented the pants and insisted that they are pure and clean and that since I have returned from Hajj, I must wear them.
And during my visit to Servat School, which has apparently fallen into ruin and given way to one of those fake skyscrapers or one-star and two-star restaurants, I suddenly discovered in what small environment we used to study and play, and Wolf in the Air and Hide-and-Seek, which I did not mention, and Castle Siege were all performed in these very small courtyards; and surprisingly, each group played its own game without disturbing the play of others, or a child getting in the way of others and causing someone's nose (or nostrils) to bleed.
And in that large courtyard of the elementary school, what other game does playing Elastics obstruct, or who does it obstruct, that you have banned it?
It is your duty to answer my child and the children of others as to why playing Elastics is dangerous.
