Is it normal to dislike someone?
Yep.Totally normal
Yes, it’s completely normal to dislike someone. You don’t have to click with everyone, and the feeling itself doesn’t make you a bad person.
People rub each other the wrong way for all sorts of reasons: clashing personalities, different values, or something they’ve done. Lots of people have someone they’d rather not spend time with.
You don’t have to force yourself to like them. You can keep things civil and set reasonable boundaries without being cruel; what matters more is how you treat them than whether you feel warm and fuzzy about them.
