I’m Clashing With My Older Sister After Our Father’s Death

I’m a female company employee in my 40s. I’m worried about my relationship with my older sister. We’re both unmarried, and we live together because our father needed nursing care. I’m patient and laid-back, basically lazy and not good at tidying up. On the other hand, my sister is short-tempered and has a fastidious nature. She constantly tells me to clean my room and be tidy.
