Have you ever had someone tell you something about yourself based totally on their perception of you, rather than on anything factual about you?
That would be my day, today.
It was interesting, not to mention insulting and more than a bit dispiriting.
Perception is informed by our own experiences, biases, and values, and, as such, is highly subjective. Perception cannot create facts, so, to ascribe a trait to a person based solely on your perception of them is, at the very minimum, presumptuous. In this case, I feel justified in saying it was bullshit-level arrogant.
I don't however, hold any animosity against the person with whom I had the interaction; it's quite obvious that they were speaking from a place of deep, deep insecurity. Or, that would be my perception, anyway.
Yeah, see how that works?
