Sometimes I don't understand people. I work with the public, I see them all the time, I talk with them, I answer their questions. Granted, it's a specific type of interaction, but it's still being with them for an hour or longer. You can learn a lot about someone in a short amount of time. But even then, all that interaction with people doesn't help me understand them sometimes.
I suppose that's why it's understandable for me when I get misunderstood. I know that it's difficult to put yourself in someone else's shoes. I know that even when you think you know a person, or know a little bit about them, that doesn't mean you'll understand where they're coming from.
I get that there are misunderstandings. But sometimes the reasons still make me scratch my head.
