One has to provisionally presume/assume that one at least partly understands what someone else has said/communicated in order to engage in any kind of con-verse-ational discussion at all. This applies to anyone/everyone - you too MikeS80! One's presumptions/assumptions may (or may not) change if and as a person then presents additional clarifying information (i.e. feedback).

Those who don't recognize that their perceptions/conclusions are based on presumptions/assumptions and so don't willingly choose to double-check, reevaluate and, if and as additional information 'dictates' this to be appropriate, modify their presumptions/assumptions to suit the 'reality' of their relational situation become 'ossified' characters who deludedly imagine their presumptions/assumptions and consequent beliefs are absolutely 'right', 'objective', 'correct', etc. True/real/honest/mutually edifying con-verse-eation soon becomes impossible with such as these.
