In General

[deckardcanine]

Some characters accused of having zero personality
Are really just inclined toward expressional neutrality.
They’re tolerant of many flaws and bear aggression stoic’ly,
Or else they stand by principles, defending them heroic’ly.

They can be quite emotional and talkative and sociable,
But something in their attitude is strictly nonnegotiable.
Perhaps you think consistency makes people one-dimensional.
It doesn’t, least of all when they are highly unconventional.

They have a set of int’rests if you watch them more attentively.
They even sometimes find a way to pass the time inventively.
In short, if you like criticisms based in actuality,
Think hard before you say that someone lacks a personality.
