Daddy, Can I help?

Was in Starbucks doing some work and saw this man arranging the coffee powder package on the shelf.  To make it look presentable, this man is tapping the package at the 4 sides to make it look squarish and firm.  Than I saw a little boy was next to the man, also trying the same thing the man did on a chair (because he can't reach the height).  It was very touching scene, I should have take out my phone to snap a photo.  It reminds of my passion that I use to have,  to help "Daddy" in work.  This daddy is doing some great work, he is always looking forward for his children to come back to his present.  As his child, may be at first I don't know what is he doing and why is he doing such a thing but I was trying to imitate and want to help.  "Daddy, can I help?"
