why do people dislike people who are good at something? I say its because they want to be as good as them or they dont like the other persons success. They also could have just a common case of what we call "Hating" this is when you dont like someone cause theyre doing or did better then you are doing, everyone does it. They could also not like them because the person that is good at something brags. Bragging is not good at all maybe a little just for fun but dont take it too far. Everyone can be good through hard work just stop being lazy.
