Manipulating and hurting are two completely different things.
I manipulate people in the fun "I like to be a jackass" way.
For example, while waiting for club meeting, I finished my drink and started bonking this girl I'm friends with on the head (lightly) with the bottle. After she sat there ill-amused for a few moments, she snatched the bottle, shouted, "Give me that!" and stomped off with, "I'm throwing this away!" towards the trash can on the other side of the very large room.
I more-or-less jokingly leaned back and was like, "Thank you~!"
I manipulated this person in two ways-- I got her to throw my bottle away, cuz I knew that would be her reaction, and then the 2nd time by "teasing" that she was doing me a favor instead of herself one.
