Do you call them out directly, or should you just not let them manipulate you (e.g. "fogging")?
I'm wondering because I have read most people don't realize they're being manipulative: they've just learned through trial and error it tends to get them what they want and don't really reflect on the implications. But I'm not sure if telling them how they're coming across would be effective or if they'd just deflect and cause me more problems.
