My parents were entirely unpredictable and what they said very unreliable, which meant I became very attuned to the range of other signals human beings give out - body language or what Freud graphically called the "betrayal that oozes out of him at every pore," betrayal, that is, of what they really mean. I have that to this day, and it makes conversation exhausting because I'm listening not just to the words of the person in front of me but also to their body. It's as if there are two radio stations on at the same time.
