I’m constantly cleaning up after my roommates, “Kerry” and “Dinah,” who are sisters. While Kerry is a more considerate roommate overall, she is a messy cook and leaves spilled food/dirty dishes all over the kitchen. She’ll return to clean up later, but usually it’s after I’ve cleaned up (I need to use the kitchen, too!) and she never wipes up her spills. Dinah drives me up the wall: She’s a pack rat, never puts anything away, never takes out the recycling, dirty dishes on the counters, etc. They’re both aware of how much the mess stresses me out. Kerry sometimes cleans with me during the week, but Dinah cleans irregularly and follows me around the house to talk at me while I clean. I’ve spoken to them both about wiping up spills and washing dishes (we don’t have a dishwasher), but after a year I still feel like their maid. Should I break down and hire a cleaning service?
