It's all a matter of interpretation.

Alice makes a statement which originates in her personal perception of reality. Bob hears the words that Alice says, but his interpretation is grounded in his own perception.

Who can say if Bob understands what Alice really means?

I suspect the answer is “nobody”.

To have such understanding one would have to have intimate knowledge of the psyche of both Alice and Bob. Yet, neither Alice nor Bob can have such knowledge.

How could any third person have such information?

There never was nothing.
