Why do I sometimes get annoyed by extroverts yet somedays I can totally see where they are coming from?

Please allow me to simplify. There is someone on FaceBook who for the most part is an extrovert. I get it he has to push his music and is kind of a louder personality. Most days I can totally take it in, and I understand the context of it all. But every once in a blue a moon I’m just over whatever it is he is speaking about, music wise, life wise etc.

But then the next day I’ll totally be like, “Oh I understand why he’s the way he is, and I can appreciate that.”

Maybe what I’m really asking is, how do I get rid of the negativity when I perceive him as annoying.

Is it a reflection upon myself that maybe it’s because I’m not involved in what he’s doing, or along the same theme?
