Weird??

My husband's mom and dad are very weird his mom trys to keep up with teenagers lives as in teenage boys she saved a pic of a boy in high-school that went to my husband's school who is still underage in her phone and was making memes out of it and she also has a daughter thats in high-school and her daughters boyfriend lays in bed with my husband's mom and so does my husband's friend. I find all of that extremely weird because her daughters boyfriend has slept in the bed with her as well. With the daughter in the bed as well but its still very weird and she talks all the time about how my husband's dad is gonna leave her for a teenage girl because they both have had weight loss surgery recently although it wasn't needed and he talks about girls even ones that are teens which makes my husband and I both uncomfortable. I just don't feel right around either of them.
