I sat on the same seat, in the left-hand corner at the back, seen from the front, and I behaved in the same way: spoke up during lessons, discussed what teachers said, got into fights with other pupils over political or religious issues. When the breaks came everyone in the class joined the crowd they belonged to or the friends they had from before, and I invested all the physical and mental strength I possessed into avoiding the humiliation it was to be left standing somewhere on your own.
