Manipulative people latch on to empathetic targets and exploit their innate qualities. They find people who are easy-going, gentle and kind - who avoid conflict and seek to make others happy. The Problem: They reciprocate none of these things.
Sometimes you just have to accept that some people are shitty humans and stop trying to see the good that isn't there. - It's takes a lot for me to believe someone is a shitty human being, but once I do, I'm done.
