Unfortunately I've had this happen multiple times where I'm just NOT comfortable around someone for reason I can't explain. And then something happens that prove that that person was either not a good person or should not be trusted. INFJ Intuition
I like this. It reminds me of a quote that a college friend gave me once: "People are going to talk about you, especially when they envy the life you live. You affected their lives. Don't let them affect yours."
