why not clean up after yourself

So I came home from school today and the house was a fricken messsssss!! My mom works second shift now so my little brother and sister are home to do whatever they want. What they're forgetting is I will be on their ass if they misbehave. I told them them to clean up their messes along with the rest of the house and if they were to do so? Well I was going to beat their asses. Scared that I will, they cleaned. If they were to clean up after themselves without being told, I wouldn't have got on their case. Little kids nowadays don't care about anything. It's sad sometimes haha. So never should you ever leave your mess around. Especially bowls and little things. I mean, don't you want to live in a clean house? It's your house too so just keep it clean please.
