Just to start off the bathroom door wasn't closed bc the lock is broken. So i (f) was in toilet in the morning and my sister half opend the door on me, so i unintentionally screamed (like super loud). And for obvious reasons she got very startled and scared. At midnight she asked me to apologize to her bc i screamed(?) and said her heart was beating so fast for like 10 mins. I told thati think that screaming wasn't wrong of me at all it was just a natural reaction, but she said "well I wouldn't have screamed if i anyone walked on me, and waht you did was wrong" so we talked back and forth for couple of mins(don't remember exactly what i said but i raised my voice and i agree that was wrong) but then i told her that "i will apologize bc i scaed u but me screaming wasn't out of place at all" but she still insists on her pov(?). So as much as silly this situation is i really wanna ask if I'm actually the bad guy here???and should apologize fr?😔
