There are a lot of things we don't need but we still exist with them. 

An old watch whose needles have stopped telling you that you have grown old.
The old clothes which refuse to button up.
The old mirror with the crack.
The old church that has been a witness to prayers galore.
And then there are some relationships, which seldom leave us.

But we all feel good, when we let them go. The tears that welled up the eyes help. It's so important to let them "out" for...a better life.
