So for the past month, I have started wearing "blue" glasses - I can see but you can't see my eyes.
It allows me to go into the office and never have to look at anyone while appearing that I am and when I am on camera I can do the same - why you say - your eyes are the mirror to your soul and I don't want to give away an ounce of what I am thinking.
When asked about it I use various reasons, my eyes were just dilated, the screen glare is really a problem, lights keep flashing in the office, etc. Rinse and repeat. I nod, slightly smile when appropriate. Put my headphones on nod my head. Say out loud "sounds good, I agree, good point...when I am NOT HOOKED UP TO ANY CALL - it just looks that way.
When on camera I do the same thing and if asked about the glasses I pretend this was the first time I had to use them. If challenged I say oh that was probably my reading glasses or sunglasses. Sound childish maybe - but I keep my sanity - quiet quitting
