ugly or pretty

so we see not a very pretty girl(cuz I don't like using the word ugly) that searchs for an honest opinion how she looks(cuz she has been called ugly/sm called her ugly) and everyone is there "oh you are so pretty,so adorable" ,and than you see a pretty girl that searchs for an honest opinion how she looks (cuz someone called her ugly)and everyone is there like "shame on you,you want attention,you are fishing.you have an ugly personality!" ...so why this happens?!🤔
