This was a teacher that told me in the 90s. “Phone calls are an invasion. When you call someone you’re saying ‘stop everything you’re doing and talk to me’. This was specially true when Caller ID was not a thing.”
Leaving a message equals to a DM or text. The recipient can respond later, but a call, it must be at that moment. It’s synchronous.
And I just saw on the news that it was the helicopter’s fault.
