Do Not Speak Of It
It is so easy to believe we actually understand what we thought we saw (feel free to fill in the implied blank). Snap judgements based on witnessing a few moments are never wise, or kind, and could prove destructive. So whatever you saw, do not speak of it. Rather, try to understand it, preferably with an open mind.
Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won’t come in. ― Isaac Asimov
