To many broken promises makes people aware of your broken promises.
One, which will be attached to your name.
And failure of  broken promises, keeps me remembering your name.
Whenever you need a favor.

This, I forgot, won't keep working.
Once it happen again.
Broken promises has cost many people loyal friends.

The word trust won't be linked to your name.
As much, as the word blame.
Failure of a broken promises will never fade.
