And this dad turned a note to his kid's phys ed teacher into a work of dad art:
It reads: "Please excuse [his kid's name] from physical activities involving standing, running, and walking [due] to foot pain. However, if his foot falls off he won't be in pain any more and is free to partake in normal activity."
Sadly, I have to agree. Falling asleep that soundly whenever you feel "tired" and having it happen during mentally stimulating events is a sign of narcolepsy. It's nice the family has adjusted to his particular health need.
