I had a similar situation. Was trying to help out a couple that needed a place to live until they found their own place. We invited them in thinking "OK, a few weeks." Well, they were "saving" up while we were doing all the food and covering everything by scrimping. The day that broke my back was when I found out they had gone out to eat at a fancy place to "get out for a bit and relax." I pointed them to the "for rent" adds and gave them a week. There is a limit.Oddly enough, I don't have any first hand stories about guests, but my niece told me one about my sister, (her aunt.) My sister, I'll call her Sally, was going through a rough patch and my niece invited her to stay with her until she sorted things out. So Sally came to stay for an undetermined amount of time. At first things went smoothly, but then Sally started complaining. Sally is very good at it. She didn't like my niece to play music too loud. She didn't like the smell of bacon cooking, because she had sworn off pork. She didn't like where her bed was and wanted to change it. After a huge blow out, Sally had to go.
LOL My mom used to walk in with a can of Lysol. Very reassuring. lolMy Mom's oldest sister, Blanche. She was a school teacher for 70 years, and was very bossy. She was the kind of woman who would come into your home and rearrange your furniture. She'd also ask personal or impertinent questions without hesitation. My Mom put up with her for forty years
