I hear ya! When my friend became a single mother, she decided to take in boarders for an income along with caring for her father-in-law, which pays. She mostly sticks to university girls who come over for a semester at a time from various countries. It is fascinating and fun for her and her son. One time, though, she had an older woman from another country living in her house. This lady was what most of us Americans would consider OCD in a big way. Among other things, she did a load of laundry every day (SMALL, TINY loads....just for herself) and washed her own dishes frequently (good thing!) and she would freak out if anyone else's towel touched hers in the bathroom. There are only two rods and four women living in that part of the house. Oh, the drama we heard about from our newly single mom friend! Between the cooking and the laundry, my friend just could not handle it anymore. She had talked to this woman many times and each time, it would get better and then gradually get worse. My friend finally told the woman, nicely, "These are the rules and you'll have to live by them or find another place to live." (Her rules were very fair and few.) The woman decided to move after a month of the enforced rules. We're pretty sure it was a cultural thing and it was for the best they parted ways. Too much clashing of lifestyles is just not conducive to a happy home, kwim? You deserve to have peace in your home.
