That's a great question. Influence and manipulation can be subjective terms, and where one ends and the other begins may not always be clear-cut. In general, influence refers to the ability to affect or sway someone's opinion or behavior through persuasion or suggestion, while manipulation implies a more deceptive or coercive approach. Manipulation often involves using tactics like lies, threats, or other forms of coercion to control or deceive someone. Ultimately, the line between influence and manipulation depends on the intention behind the action and the impact it has on the person being influenced.
