The thing is, if you go into a conversation expecting to be viewed negatively, it's going to impact how the interaction goes.

How else can I be viewed? Joining someone else's conversation uninvited is very impolite. This is not acceptable behavior. It's annoying at best, creepy at worst.

And at that point, you're actually seeking a therapist anyway.

Therapists are charlatans. They aren't real doctors. They cannot heal, they cannot prescribe, they cannot operate.
