life of a 4 yr old

Today was a rough day for little RyRy. We were at a friends and when it was time to leave, Rylan decided he was not. I asked him 2 times to get up, put the toys down and walk out the door with me. He preceded to throw a fit and wine. I told him if he did not come with me he would get a spanking when we got home for not listening. We do the Accountable Kids program where you take tickets away for things like this, but unfortunately I forgot to say he would lose a ticket and spewed out spanking instead. What was I thinking?? Either way I had to follow through with what I said. He had his big wheel over there and I told him to get on it and ride home. He stomped and cried and said no. I asked him one more time and he continued to act out. So I picked up the big wheel carried it over my head and walked across the street to my house. He screamed, cried, and through a fit all the way home. Middle of the afternoon, quiet neighborhood...screaming child...oh yea...I'm evil. How embarassing! I told him to go to his room and he was having a major tantrum and said NO! I went to get the spoon and give him his spanking. he spent the next 15 minutes there. When he came out of his room he said he was sorry and he was now ready to Listen! I had to laugh. Why dont they think of that before they lash out?
