I had serious respiratory immune issues (technically still do) and I actually got in “trouble” with the principal once for missing too many days. He basically tried to intimidate me to admit I was slacking off and skipping out. I laughed and suggested he call my dad and his tone immediately changed.
This was in Canada too. That principal was a worthless sack of turd. He stood in the middle of the hallways between classes and tried to impose this grumpy, mean, “hard ass” attitude.
