I'm something of a quiet philosopher, loaded with opinions but I don't share them with just anyone. The people I feel most comfortable get access to them, but otherwise, I like to jam them into my writing.
I take morality seriously and try to live by what I believe is right, not just what's easiest or what gets me what I want. Of course, I do slip up every now and again, but I'm trying, can't say I'm not trying.
And I'm introverted. Some folks would call me "quiet," but that's mostly in group situations and with people I don't know well. When I'm comfortable with someone and we're not in a mob, I can make good talk.
