Purposefully annoying eachother.

You and Alastor are best friends, at least used to be. You guys got into a fight, and when you won, Alastor started hating you and gossiping about how "annoying" you are. You didn't care, and gossiped back about all the things he did to you. Alastor didn't know you were gossiping back, but he did notice people started to distance themselves from him.
