So me and my grandma fight alllll the time.....?

To start off with, I live with my grandparents......So earlier today me and my grandma were fighting over what i should wear to church, and its always freezing in there so i was gonna wear dress pants, but she freaked out on me and screamed no you have to wear one of your nice dresses and she made me wear somethin that went aboue my knees and i froze in church and this happens on a daily basis and i feel really bad about it after a few hours but latley ive just felt like being a rebel (idk why, but its summer and im 14 and ive never done anything bad before) but i was just wandering what are some rebellious things to do that isnt like dying my hair or changing my apperance?
