Almost every x reader leaves out things, like it says you have a brother, but maybe you don't have a brother. Or it says you have both parents. Maybe you don't have both parents. You need to try and include everything. Or what if you can't HAVE a ponytail in your hair because you have SHORT HAIR. You need to really try and put the person in the story. Even if you do, you still can't really make it for everyone. That's why x readers are stupid.
