You are a dickhead.
There was no reason for you to use the tone you used, other than to inflict emotional pain on those who heard your words. Why can’t you stop and consider how it would feel if someone spoke to you like that? Especially if that someone supposedly cares about you? No one who cares would ever say the things you said, the way you said them.
Think about that. Mull it over. Dwell on it a while. And while you’re at it- stop being a dickhead.
