Pour Thing

Why is it that my children are bent on destruction? Where does this gene come from? Is there a way to turn it off? Why aren't all the research dollars going to solve this problem? Why does it seem to be MY kids who are always pulling these stunts?

It's a DARN good thing everyone is asleep or mom would be on the warpath. Which son of mine decided it would be a good idea to pour all the sand and stones from the rock polisher down the sink?????????????
