I've come to view it as an aspect -- even if unconscious -- of competition.

The noisy folks tend to be a lot less effective (in particular, I mean those who chatter half the day away, and whose mistakes I was constantly fixing).

But... with their noise and disregard for my own concentration, they dragged down my effectiveness. (And my peace of mind and ultimately, health.)

One reason I now advocate -- strongly -- removing oneself from such environments as soon as possible.

I received a strong, sustained, and somewhat domineering message that I was the one who needed to adapt. And, being young and inexperienced and without much power, this caused both some significant self-doubt and great frustration.

I can't make up what I lost. But I can advise others to avoid similar loss.
