Older or Wiser?

This post comes with no pictures but stuffed full of brains. Today I was upstairs cleaning the bathrooms going about my motherly duties. I needed to bring something downstairs and was a little startled as I heard something in my office. I came in and much to my surprise found my 9 year old playing games on the computer. I said "I didn't know you were home, why didn't you come upstairs and say something" He said, "I smelled cleaning stuff". I said, "And" and he replied with "I didn't want to clean". Wiser??You decide.
