My favourite of all is coin - as in "the flip side of the same" which is absolutely perfect for how perception works.

Last night I heard Margaret Atwood speak about her latest book, MaddAddam (she's fond of palindromes). Although most of her books are not on my re-read list, I was jazzed to hear her in person. She was fluent, fluid, funny.
A critic might describe her style as condescending and affected, her mind preoccupied with body parts and swear words, her answers to audience questions flippant.
A fan may say she is brilliant, knowledgeable on diverse subjects, hilariously down-to-earth, and likely to turn silly questions back over to the asker.
Same subject, same event, two perceptions. I love it!
