Things You Can't Recover

The stone... after the throw.
The word... after it's said.
The occasion... after it's missed.
The time... after it's gone.

Can I add in a few more?

The relationship... after it's broken.
The friendship... after it's tarnished.
The trust... after it's betrayed.
The mood... after it's spoilt.

So much for sounding so negative, huh?
