What is the sound of one hand clapping?

Well, you know its impossible.
No second surface? no clapping; no sound.

Know that darling, you just can't think that you're the only saviour of this relationship.
Maybe you can't see the compromises I've made.
I try my best but maybe I always fail
How can't you not see the efforts I make?
Some days I acted mature when you were being dumb
Sometimes you let go my mistakes
Sometimes I forgave you

We've come so far and the reason is not just you
Its us together who have grown stronger

Relationships are imperfect.
It's just the two people who promised to never give up.
