The only thing more annoying than taking care of my fingernails is taking care of my toenails. I wish they'd just stay short and decently shaped with no help needed.
I hate how the edges of the skin like to grow over the sides of the toe nails, requiring it to be trimmed in order to tidy everything up. My ex never took care of any of her nails. She just bit and pulled on them, making them scratchy as hell. Couldn't stand rubbing legs together with her as I would always end up with a bunch of bloody scratches like I'd been mauled by a cat!
Of course, you can always find some guy with a foot fetish who will take care of them for you.
