Excuses.

We hold all of this pent up nuance inside that nobody sees, and we desire very strongly to let it out.  But when we can't get it out, or when the nuance isn't noticed when we do, or when we see other people unintelligibly letting it out--pure amateurs, we think, though we never actually practice what we may self-preach--we only have one friend.  And that friend is liquid, and goes right inside to buddy up with all of the nuance.  And it is good at smothering its buddies.  And pretty soon all of the nuance is hostility.  And the hostility is easier to let out. And the reactions are strong, but the excuses made are about how others don't understand, about how they don't see.  And the crime is that we've become blind to any nuance ourselves, but still use it as a crutch.
