“If I’m being kind to you but you think I’m being horrible, am I being kind, or not?”
Being kind to someone can mean something like being super polite, or for someone else, it could mean saying something as simple as thanks. But it doesn’t really matter what you think, most people can see a clear line between being kind and being mad. So if someone thinks that your being mean for saying something like thanks, instead of thank you. Then you know that they’re wrong. But if you do something like throw someone in the trash, and think that’s kind, you should know that’s not right.
