Well easy to say, but if you are working in the real world, then unknown callers may be important - i.e. FedEx trying to push your package through the customs and if they can not contact you, your package goes either back or is destroyed.

Legitimate callers for events you initiated leave messages. The correct avenue for critical notifications not initiated by you is still paper mail.

But your child's school nurse might not, in an emergency.

Your child's school nurse would be exactly the type of person who would leave a message

[brewdad]

Not necessarily. Ours would work down the list of numbers she had for me, my wife, and other emergency contacts without leaving a message. My wife got pulled out of a meeting at work once despite me being the parent at home because I missed a call from the school and they didn't bother to leave a message.

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.

> But you'd very likely have their number saved on your phone.

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.
