So they can't put their shoes on and they can't find an adult to do it for them (because we are actually not leaving the house)? Throw them on the ground.
They've finished dinner and the bowl and spoon aren't being taken away quickly enough? Throw them on the ground.
A toy won't do what they want it to do? Throw it on the ground.
They're being reprimanded while they just happen to be holding onto something? Throw whatever it is on the ground.
I was talking to a friend about this over the weekend. We were marvelling at how kids just seem to be born knowing how to throw things on the ground when they are frustrated. They may never have seen anyone else throwing something when they feel frustrated (....although maybe in our house they might have.... ) but somehow they just know how to do it.
It's hard to believe that kids are sinful when they are cute little babies. But the onset of toddlerhood makes it oh so clear.
