I might sound like a preppy person, or something like that when I say this. But I have never had a problem with someone's parents hating me. Everyone's parents love me. But that's because I'm not really a trouble maker. If I go to their house, I don't just visit my friends, I help around the place. My ex best friend used to come over, and my mom hated her, and so did everyone else's parents. She was disrespectful to the adults, ran around the house like a 2 year old, and went through your food, and got mad when I could get away with it at her house. Something she didn't understand is, her house is my uncle's and her aunt's house, and they take care of her. So I had all rights to go over there and raid their food. Plus when I went over there, I cooked, cleaned, and watched the baby. My friends will get mad at me because we will eat, and then I'll go ahead and clean our dishes, and whatever else is in the sink. That's also the way I get so many babysitting jobs, because not only do I watch the kids and clean up after my self, but I make sure things are spotless before I leave. I'm OCD at other people's houses.
You need to look inward as to why they dislike you. Lack of manners, unhygienic, unmotivated, bad language, makes poor choices, bad influence? Once you figure that out; work on correcting those issues.
