Sometimes informality breeds rudeness. Maybe companies that are very informal manage to keep stress levels down. But if it's very informal, workers might not know what their boundaries are.

When the healthy pursuit of self-interest and self-realization turns into self-absorption, other people can lose their intrinsic value in our eyes and become mere means to the fulfillment of our needs and desires.

....a crucial measure of our success in life is the way we treat one another every day of our lives.

They think the world revolves around them and they are not considerate. They are not kind. They are trapped in a cage of narcissism we have built for them.

Being in pain, doesn't give one license to cause pain.

Yet, sadly, accidental rudeness occurs alarmingly often. Best to say nothing at all, my dear man.
