They might not.. But you'd very likely have their number saved on your phone. Might even have them as an un-mutable contact. My wife/kids and their school are all on the "never mute" list.

I certainly don't. Every call I get from the school seems to come from a different number. And the camp she was at when she hurt her leg and had to be taken for immediate medical attention.

I get it, in your world, in your experience, it all works out. But in mine, it just doesn't. From experience, I _know_ this is true.
