Something vaguely similar but kinda inverted, happened when I was in middle school.

An office assistant, like a TA, but for the main office, was dispatched to deliver a packet of course work papers to the class I was in.

The main office had the main, commercial grade printer in it, and this would have been like… 2004 ish? Computers were basically only in the computer lab, more primitive tech setup.

So anyway, the OA shows up and delivers the coursework to the teacher… and is confused by the complete silence in the room, the lack of anyone doing anything.

He remarked ‘… Did somebody die or something? Jeez’ and was now met with many intense, silent stares… and quickly exited.

Completely unbeknownst to the OA… about 15 minutes prior, our teacher had just recieved an email, took aside one student, talked to him for a few minutes. That student then quickly talked with his friends for about a minute, eyes tearing up, getting several hugs, and then presumably left to the school counselor office.

His one or two grade older sister had just suffered a complete cardiac arrest in PE, out on the track, about 30 minutes prior to the email… and died.
