It’s really very easy to understand. When someone gives you the same crap back that you just got done giving someone, you don’t like it and act like that shouldn’t happen.
I just see, in what you're doing, a wild lack of self awareness. You're criticizing me for doing to someone else a milder version of what you're trying to do to me now; I'm genuinely confused how you can't see that, or how you could possibly stand the hypocrisy if you do understand that.
