Well, I don't hate anyone cuz there is no reason to hate anybody plus Hate is a strong word. I would use strongly dislike. But If I would say something nice to someone I strongly dislike, I would say " Hey, You look really nice today" or " Hey, I hope you have a Wonderful Day". Say something that will make them smile, make them talk to you. Once you get to know the person you strongly dislike, you'll start to like them cuz of their personality. You can even compliment them like " I like your shoes", " I like your shirt ", or " I like your hairstyle ". MAKE SOMEONE DAY AND MAKE SMILE
