You can unpack it: "You have made this person unhappy, and you didn't notice. Here are things that you may not have noticed about this person: X, Y, and Z. They see this encounter like thus-and-such. Now that you know that, you can interact with them in a way that makes both of you happier."
Some people observe that more easily than others. It seems to be the case that some are neurologically lacking the ability to do it at an intuitive level, though you can do just as well with conscious observation and rational conclusions. That is more effort, but "whoops, it's just too hard" has never been a good excuse for anything. It gets easier with practice, and when you're too tired to make the effort, you can learn tactics to cope. (Such as, "Hey, I don't think I can have this conversation right now. I'm sorry about that. Can we please resume this later?")
Too many people, including some very prominent ones, have decided that any effort is too much, and that they are better off being dicks. I can't necessarily refute that. But I can say that if you're a dick, people are going to treat you like a dick, and that is likely to end badly for you.
