Should We Ever Take Anything Personally That Has to Do With Other People's Behavior?

I recently got an email that I found pretty upsetting. It wasn't from someone that I know, but it was very sort of critical and a bit accusatory. My big question is, should we really ever take anything personally that has to do with other people's behavior? That's a great question. Yeah, sometimes it really is about someone else. But if you find that somebody is having a strong reaction to you or what you're doing or the situation...it's only natural to look at yourself as well.
