I know it's so cute, hence my avatar. It's so nice when you sit beside a villager on a bench and it makes them so happy, I always feel guilty when I have to get up and leave them.
For me its digging things up. For instance, i dont allow normal flowers to grow so i just dig them up instead of tediously selling them at re-tail to get rid of them. It satisfies me when there's no more fossil marks or odd flowers, its one of my daily town "chores" if you will.
