my sister lives with my bf and I and while we are close she is in a different phase of life than i, she is recently divorced and dating again and while there's nothing wrong with that she is high maintenance and moody and sometimes I cannot handle her. maybe it's hormones but sometimes I just don't have it in me to hear the stuff she complains about. plus she had nowhere to go after her divorce so I told her to move in with us, but she doesn't pay rent and she goes to school. in exchange she cleans the house and cooks which is so kind until she gets a job but then she loudly exclaims, "I cleaned everything!" as if I never clean a day in my life. sorry if my griping makes no sense but I'm just hiding in my room today.
