As I've mentioned before I do not really get angry. I might get irritated and such but for more then 10 years now I have been unable to get angry. I do not express much feelings at all in fact even those that I do feel. But anger I can not even properly feel for some reason.
Perhaps my amount of self discipline and accumulation of information has somehow reallocated some neural processes that are involved in anger for information processing. When I sometimes feel like I might be getting angry at something then instead I have this little "zap" in my head and it all defaults to 0. It causes a feeling of slight discomfort like someone poking you in the eye would do.
And funnily enough my father is a short tempered man always raging at things, object and random people. My mom is a sort of temperamental woman and keeps telling me that I need to get angry sometimes too to get people to realize the severity of the situation. I do not though, I literally seem to lack the ability.
