Interesting point. I would argue that people don’t hurt you. We hurt ourselves when we project or expect certain things from people. I’m not arguing for a nihilist approach but still, the hurt comes when we put an expectation on someone and reality fails to materialize.
Should we then distrust people? No. It’s about being non-judgmental, which is one of the hardest things to do, as humans are wired for this.
Still, if you just regard a person as a person and don’t paint them with any color, things become simpler. If they deliver, then you’ll be joyful, if they don’t, well, it wasn’t unexpected either.
Hope this makes any sense.
