Language is a tool that humans use to interact with each other, if you can&#x27;t use it for this very purpose, then you&#x27;re the problematic one.  In written language the product can be revised and rephrased many times to arrive at a mostly unambiguous result, but with the spoken language, the product is produced and consumed contemporaneously and spontaneously.  Ambiguity is in the nature of it: nobody has the mental capability to construct non-context-dependent, logically-completely-unambiguous sentences in the context of a casual conversation.  You have to learn to differentiate among various linguistic contexts and registers.
