You poor thing! What if you were the teacher and had to keep up with yours and every other kid’s papers!
Haha, but with all due respect, this is a different issue.
To expect that parents will get every form, that they will sign every form, that the kids will faultlessly return every form, and that the school will properly file and not misplace every form, is a bit naive. It is also short-sightedly authoritarian and legalistic to put the presence of absence of a particular form in the legally superior position of gating potentially lifesaving medical help to a student in need.
