Your're a Liability: The Question of Responsibility

In terms of probability,
Yes, you're a liability.
You've lost your credibility,
No longer show humility.
With incompatibility,
It's an impossibility.
Why is my gullibility
Linked to responsibility?
Where lies respectability
And your believe-ability?
With such predictability
And your destruct-ability,
You've lost desirability
Because of instability.
In terms of your gentility
And your lack of civility,
There is still culpability,
As well my tranquility.
With no profitability,
And unreliability,
Plus my vulnerability,
And gentle sensibility,
I question suitability
And your dependability.
In terms of eligibility...
A lack of feasibility.

How do you tell someone that they are a liability to you?
