Should I be nervous about this?

Both Noah and Adam have a box in their room where they keep trinkets and other special things. They call them their "special boxes". Honestly I am such an anti-clutter freak that I started these boxes because I had thrown away a lot of things that they really wanted to keep. So, I tell them that I can't tell if it means anything to you unless it is in your special box. So, the other day Adam with digging through his box and playing with things and reminiscing about his special things. He found a self portrait that he had done when he was 3. He pulled it out, examined it carefully, made a disgusted face, and brought it over to me. He says,"Mom, can you throw this picture of me away. I don't want it any more. It makes me look fat."
He hands me this picture and walks back over to his box. Should I be worried??
