About a week ago, Puck moved into my town after my friend came over to visit. I was interested to meet Puck, but when he finally moved in, his catchphrase "brrrr" was changed to a swear. It's obvious that my friend changed it when Puck used to live in his town. Is it possible that I could get into trouble from something I didn't do, and if so, any way to get him to stop?
