The former is what I'll end up displaying most often. It's much more vocal and much more physical (that is, the non-verbal physical characteristics can usually be picked up in my face or what have you), and, ultimately, it's little more than hot air. It's usually a knee-jerk response which blows over within a matter of hours, or, at the most, a day or two.
The latter, on the other hand, is a different matter. The latter occurs very rarely, and is typically reserved for only the greatest of travesties. It is much more intense, but, perhaps because it runs much deeper, it is easier to keep below the surface and is harder to pick up on. Often, I will be very un-vocal with this mode of anger; if anything, I will either be stone silent or unnaturally calm. This does not simply boil over; this kind of angry can fester and bubble for years as I wait in the darkness for the perfect opportunity to wreak havoc upon all the Earth.
This is the kind of angry you don't want to make me. This is the kind of angry you don't want me to be.
This is the kind of angry I am.
Ericson, you've really fucked things up this time.
