I unironically tell people its “my pleasure” when i do things for. I enjoy helping people, even just holding the door for you while your hands are full makes me feel good. It literally is a pleasure to me.
Its regularly met with, “did you work at chik-fil-a?”
Testing people like, “i put them in a shitty situation like pretended to cheat on them and see how they reacted” is shitty and manipulative.
Observing someone and how they process a situation is not manipulative.
