Rage is misery that does not know where else to go. Sometimes I think rage gets mischaracterized as necessarily loud or shouty. If the rage-burdened person tends not to be loud or shouty, though, it can also manifest in other ways, as it did with me: as brittleness, or constant irritability, or extreme irascibility, or tetchy irrationality, or a total failure of self-control, or even all these things.
