At some point during the third grade, a new hobby emerged among the girls. They started collecting rubbers. They bought them in all shapes, sizes and patterns and then started exchanging them. All of them did it.
We really didn’t understand it. So the Lindens started a protest movement. They bought the finest, largest and most exciting rubbers and then used rulers to saw them into tiny rubble. This greatly angered the girls, as they saw it as wasting good rubbers.
Soon a massive rubber black market erupted. Girls were trying to exchange their more boring rubbers into the beautiful ones of the boys in order to try to save them. The boys then cut the beautiful rubbers up for scrap in the front of the very eyes of the girls. Another fine option was to trade a big, beautiful rubber for several tiny ones or blackmail one of the girls’ favourite rubbers in exchange for saving the big ones. And in the end again cut up everything that had been received as a trade.
I think the whole thing ended, when the girls complained to Zach about us destroying beautiful rubbers. And in the end the Lindens got detention for having their school desks so full of rubber rubble, that all of the homework they returned was all messed up in it.
