I think I might actually despise old people
Why do you hate them?
I hate my aunt for being old.
I can understand disliking a family member for their actions, but you can't control your age. Hating someone for being old rather than disliking them because of something they did to upset you seems shortsighted.
Those old people are just a waste of resources and time. They can't even do simple things on their own, I have to take care of everything for them. They stay up all night and sleep all day; that is so wrong.
Old people are just as human as you are, and needs change as you get older. Soon enough you'll be feeling the same way, so why not try to be a little more sympathetic? Your aunt would appreciate everything you do for her.
