People will dislike you and don’t have a valid reason as to why they don’t like you

I can relate. There's a lot of people I know from school or work who I dislike, but they've never done anything to me. I don't really have any legitimate reason to dislike them. But I also fully recognize that, and so I go out of my way not to let my bias against them affect how I treat them. There's no reason for me to be rude to them.
