I told him not to do it, and I told him that if he did do it, he had to clean it all up afterwards, and it was going to make a big mess. So he did it, a few times, and then he wanted to move on to something else. I told him that first, he had to clean up all the stuff he did, and he commenced whining. I explained that I had warned him of the consequences prior to his actions, he said, "I know," and did it anyway, so now he had to deal with the mess. He grudgingly started picking it up. Eventually, he complained that it was taking too long. I repeated my small speech on the consequences of his actions and agreed to help him. Soon, he said, "This is making me tired." I told him that if he was tired, he could go and take a nap. He stomped off to his bed. After a few minutes, he came out into the hallway and looked at the floor, where the mess remained. He looked at me. I said that he still had to clean up his mess, I wasn't going to do it for him. He whined and flopped onto the wall. I said he should just go and lay down if he wanted to act that way. He is now in his room where he is fake crying with brief bursts of quiet to see if I have relented and am approaching his room.
This is the first time I have had to write in weeks.
And I will still have to clean up most of the mess.
