I have one who dislikes learning. It took the better part of an hour to force him into some sort of task compliance! My most annoying though so far would be the children who dislike running, lol. I even named the one girl Slow Poke. Just so that when I clicked on her to grab a mushroom or item, I'd remember not to use her, it takes her forever to wander back to where she's going.
There is only one solution for a lazy girl like that - keep her pregnant once she comes of age. My lazy girl crawled everywhere and refused to work unless babysat constantly. But once she put a kid down, you never saw anyone run so fast - for the closest male!!! Oh the terrible things I have called her - Jezebel being the only printable one!
As a mother and grandmother, I was a little put out by the utter USELESSNESS of nursing moms. But I decided to give the folks at LDW the benefit of the doubt and see the moms as too busy for such menial tasks rather than useless.
Seriously though, all the lazy ones are good for is making babies!
