Yes, I vaguely remember when I was in maybe 8th grade at the little school in San Salvador, we older kids congratulated ourselves by tilting our chairs back, leaning back in our chairs only slightly, which if you have another desk or shelf behind you, could be arranged not too dangerously. However, a younger girl in the classroom tried to imitate us, not having anything to stop her chair from clattering to the ground with herself in it and that was dangerous, she could have really hurt herself although in reality she was not so much hurt as shaken up, and so the teacher, Mrs. Richardson, berated us for setting a bad example for the younger children, and she had a good point there, so we had to stop doing that.
