Why is it so easy with some people?

Why is it so easy with some people? The answer is simple: they are tactful. I genuinely rejoice when I see that someone has reasonably and timely refrained from making a stupid comment, inappropriate criticism, joke, or any other unnecessary display of tactlessness. Such people are intelligent, possess restraint, and have the ability not to put themselves, you, or others in a ridiculous situation. Therefore, it is easy to find common ground and communicate with them.
