Noticed 24-27 year old suck

Iv noticed that people aged 24-27 suck, i can make amd ne friends with people older or younger. Have lots of friends older and younger, but it seems theres a weord gap i cant understand. 24-27 seem to always no matter what assume ill intentions from any kind of nice act or are incredibly transactional. Or have a weird moral ocd that lacks any kind of nuance, like wont be friends with someone if they date someone 4 years younger, or just weird thing. Yet I dont see it in younger or older than that, iv had lots of very odd experiences with people in that age. Im 26 so I fall into it, but I bring up my experiences with older/younger and they find it odd. Yet I bring it up to people in that age and its ok? Especially when it comes to things like selfishness or being ok with very transactional relationships, i wonder if covid really messed us up, idk its frustrating and weird
