Similar Dissonance

It's an odd sort of relationship they have,

A similar dissonance really.

In the way they act;

Oddly the same but drastically different.

Everybody notices it.

Well, to be fair everybody but them.

How could they, when it's a similar dissonance?

Authors Note: Yes I realize it might not make much sence - I actually got the inspiration to write this from a story I am in the middle of writing. Maybe it'll be good, but maybe not. Eh.
