<human>: So my girlfriend and I were having a long discussion on our relationship, and eventually we moved on to stuff that bothered us about each other, and one thing she said that its sort of off putting that I never really get angry. I asked if she meant, well, does it seem like I don't care, or...? And she meant 'No, I know that you care, whether we get into disagreements or not, but you never get angry, and I do, openly, and I think that's sort of weird!'

I don't know what to think. Yes, it's true that she's moodier than I am and she's open and vocal about things that anger  her, but I guess I'm...not? I'm honest about things that bother me and yeah, we do have disagreements and it's definitely NOT a relationship where she's stepping on me (or vice versa), but I suppose it's true that I rarely ever get outright angry. 

The way I view problems is 1. Can you solve them? If so, solve them. 2. Can't solve the problem? You're an adult, deal with it. Getting angry at a problem you can either solve or not solve doesn't accomplish anything and the problem is still there. I feel if I get openly angry, I'm losing control. Note that I don't think this makes me a 'better person' or w/e. I'm still generally no less or more of a regular ass human being like everyone else.

I dunno, I'm definitely not robotic or stoic, I laugh, crack jokes, am social, the nine, I'm a normal guy! But I pretty much NEVER get openly angry. I know its a natural emotion, but I myself never really saw the point in it to express outwardly myself. Is my girlfriend right to feel the way she does?

Could you distill the essence of the text into 1-3 sentences?
<bot>: girlfriend is sort of concerned that I don't express anger. I'm a naturally calm guy to begin with and I was raised to view that getting outwardly angry is generally childlike and doesn't solve problems. Thoughts?
