"Daddy, let me tell you something."

Our local mall has a small playground (indoor) and it has been baby's favorite place to visit. Today we went there after dinner. After running around for a few minutes, he walked to me and said, seriously,

• "Daddy, let me tell you something."
• "Yes?"
• Look, there is something wrong in this place.
• What?
• There is a lot of trash on the ground. It is not right.
