I’m a very very sassy person. It’s a trait I’ve had since I was very little. Let me tell you a little story. I was five or six, and we were on the way to the zoo or something. I was tapping on the car window, and mom told me to stop she said, “what are you going to do if you break the window?” I answered her, “I’ll enjoy the fresh air.” That’s just an example. If you are insulting people and you mean it as a joke, they recognize it as a joke, I don’t see a problem with it. When I do that to people I always add “I’m joking I’m joking” even if it’s blatantly obvious that I’m not being serious. Just know when it’s appropriate to do that, and there’s always a line you shouldn’t cross.
