This bothers me so much!!!!!?

I babysat a 3yr old and he would nottttt listen to me! He kept running away, breaking things, spilling juice, letting unwanted guests in, and, worst of all getting naked. I couldn't get him dressed. He was a monster!!! So how do I keep him under control? Any tips? And how do I not be so bothered from seeing him naked? It haunts me constantly, I feel dirty and gross. How do I feel better and do a better babysitting job? Thanks sooo much!!!
