trust rotted

Why is trust?
Treated like a piece of rust,
Something cut out and thrown away,
Left to rot til the end of its day,
Not needed anymore,
Just thrown on the sea shore,
Given to someone to hold,
Though it can’t be bought or sold,
It can be broken,
Or traded for a token,
Is it so hard to say no?
Or you don’t want to go,
Tired of hearing lies,
Hanging around like a bunch of flies,
So I guess they’ll give up any chance,
Of someone to join in them in the dance,
Left to their own,
To be the one that’s unknown,
No longer has it seemed they can trust again,
Your heart’s thrown and left to rot in the compost bin.
