Suddenly, Nick's Barrier shone with a yellow light, but no one paid attention to him.
By now, Nick was no longer even part of the entire discussion.
His discussion with Cynthia had been infiltrated by several Zephyx Engineers, and they were all debating math and Zephology by now.
Nick wasn't even really sitting in the middle of the circle of people anymore.
Just like everyone else, he was in the audience.
From time to time, some of the Barriers turned yellow.
When a Barrier just randomly turned yellow, it meant that it was time to meet the supervisor.
Everyone had to meet the supervisor once a month for a quick interview, and now, it was Nick's turn.
This entire debate about Zephology and math had been going on for weeks by now.
It wasn't always the same people talking.
