I didn't know you were chill like that
This happens when someone is being a total pain and then acts like they're the king of chill.
You were screaming at me like I was your arch nemesis. Then you gave me a peace sign. What's with you?
You were yelling at me in traffic. Then you did the hang ten. What's going on?
You were cussing me out for no reason. Then you just went chill. Are you messing with me?
