How have you dealt the inconsiderate friends of your children?

My 11 year old daughter has a friend who is just perfect for her. They’re in GT classes together, and they were in the same elementary school, so they’ve been friends for a while. A couple of years ago we started doing sleepovers, and I discovered this kid is incredibly inconsiderate. Apparently she does not behave this way at home, at least as far as my daughter has seen. When she’s been at our house she’s done things like drop pizza on the floor, sauce side down, and just left it to sit (on new carpet!), decided she wanted to eat her ritz cheese crackers like a dog, so she dumped an entire bag out on my couch and proceeded to eat them with her mouth, leaving behind a saliva and crumb mess embedded into the fibers. She regularly leaves her trash wherever it falls. I find all manner of food in couch cushions and on the floor when they leave, even when I’ve specified that they need to keep it clean.When we have sleepovers I always take the kids to the grocery store to pick out snacks, because as we all know, good snacks are a cornerstone to a good time. I don’t mind they go a little crazy, but the last two times we’ve done this she’s had me buy dog treats, which I thought were meant for my dogs, but that she never opened and planned to save to take home to hers, and just last night she was picking out snacks, and my kiddo said “hey, you’ve probably got enough,” she replied, oh, these aren’t for the sleepover, these are for my house. I kept my cool, but I told her I wasn’t buying snacks just so she could take them home.I’ve been to her house. She’s not neglected or staving for food or attention. To the contrary, she’s somewhat spoiled with both. She’s just got shitty manners when she’s away from her parents. I’m at the end of my rope. I don’t want to forbid the kid from coming over because she and my daughter have so much fun together, but I don’t think I can handle her entitled, messy behavior again.How have those of you in similar situations dealt with someone like this? via /r/Parenting https://ift.tt/3iviFjz
