Because a dear friend, 
This is our four year old, so enthralled to use his dad's sunglasses, trying to be as "handsome" as he can be.
It is so heartwarming to see our little fellow copying his dad and acting like a little adult. Yet, this is a constant reminder for us to behave properly, because children are keen listeners and observers and are quick to imitate our example.
It is a challenge to raise a child, especially protecting him from moral danger. Only by pleading to Jehovah God to instruct us how to be good parents will we be able to be successful in this difficult assignment.
