Do you feel uncomfortable when you see someone else being embarrassed?
This is very situational dependent. If its done unintentionally in a professional setting, then yes.
However, in a playful social setting, different expectations prevail.
What’s most likely to make you squirm?
When people throw themselves under the bus.
My rule is that I will never intentionally throw anyone under the bus.
But if/when they throw themselves under the bus, I reserve the right to not stop them.
