Sing about my day

Grant is the king of stalling when he's going to bed. He asks for water, begs to brush his teeth again and requests us to sing songs while we play with his hair. He consistently makes the request, "sing about my day." We have to pick a catchy tune and recall all the fun things he did throughout the day. When we leave him in his bed we remind him to think about his favorite things.Tonight when I got done he said, "but I don't want to go to bed. I don't want to think about my favorite things. I can only think about sad things. I was tired and not up for cheering him up so I said, "fine. Just think about sad things." He got all cheerful and said, "okay. I'll think about disobeying, that is very sad." (said with a grin)
