I got the HR complain after 4 times I think :)
The cost of free will is to sometimes be difficult to understand for other people.
My webcam is always off. Nobody expects me to have it on anymore. In the beginning I got a few questions about why. I said I don't like how I look on camera to other people. Nobody even tried to convince me to have it on.
You are not an adult until you learn to do what you want and handle other people's opinions as exactly that - their opinions. Its what they want, not what you want. The difference is very important.
Tldr... Grow balls, learn to do what you want and be OK with what other people may think. After a few days or weeks, it becomes normal for them and they can focus on other important topics like who wins the bachelor this year.
Social groups must have highly variable definitions of adult behavior.
However, my camera is off when I haven’t had time to take a shower, a dashing down the hall for a bio break, and many other times. When I talk with my hands too, my camera is definitely on, and I appreciate the nuance of others’ facial expressions.
