Has someone tried to piss you off on purpose to get a reaction?

Some of my peers known me as a sweet, nice and kind girl that rarely gets angry unless someone pushes the limit. I’ve had family members piss me off purposely just to get me to stand up for myself. One of the guys (let’s call him Dale) I knew from high school said, “I’ve never seen you angry. I want to piss you off on purpose so I can see how angry you can get. You’re too positive and too nice.” Dale kept poking me so much, it bugged me so bad. He kept doing it and doing it until I snapped! I screamed at him so bad that he was left scared. He told me to get out of his face. I told him to stop and Dale said, “Finally you’re angry! Good I wanted you to see you pissed! About time!” I couldn’t stand him. My best friends warned him that I can get ugly when I get angry but he didn’t care. Well I haven’t seen that idiot since last year after we graduated.
