"Guess I Was Too Busy Being In the Now"

Don't we often wonder whether what we share with our children ever truly sinks in?  Several days ago Kim was driving our 14 year old son, Jonah, and a few of the neighborhood boys to school.  They were all talking, laughing, and clearly enjoying their conversation.  After Jonah exited the car, Kim noticed he didn't have his backpack and upon quickly scanning the car, realized he forgot it at home.  She yelled out the window but he was still so engrossed in conversation that he didn't hear her.  She pulled around to the parking lot and phoned him.  A minute later he returned to the car and she asked, "Missing anything, Jonah?"  He replied, "I don't think so."  "Your backpack silly", Kim announced.  They rushed home and made it back to school just in the nick of time.  Just as he was stepping out of the car once more, Kim asked, "Jonah, how did you not notice at any point that you didn't have your backpack with you earlier?"  He paused for a second to think and responded while laughing, "I don't know mom.  I guess I was too busy being in the now.  Maybe this incident will be a good post for Daddy's blog?"  "I think you're right son.  I think you're right."
