I think a good way of stating this is that no two people speak exactly the same language. Even where simple terminology is concerned, everyone defines the boundaries of meaning in slightly different ways, and attaches their own particular connotations. Most people will have the 'center' of their understanding of a given concept close enough to those of others' that the general case of communication is almost always satisfied. But in specific circumstances, as the need for precision in meaning increasingly presents itself, so too does the likelihood of an edge case in which understandings don't overlap. With this in mind, a lot of the process of 'getting to know' someone can be construed as learning their language, in order to enable effective high-precision communication.
