Positive interactions

I witnessed a very unsettling scene today.  I saw some adults who were supposed to be caring for children, yet the only interactions were negative.  If I heard the word "stop" once, I must have heard it twenty times.  Eventually, it morphed into a clenched-teeth "schtop."
There wasn't a whole lot I could do, and I knew what I could do in a brief window of time would not over ride the day to day experience for these kids.  I just wished I could tell the adults to make sure that most of their interactions were positive.
A child needs a smile, a child needs a hug, a child needs encouragement, a child needs guidance. 
When you see a child who has been loved and nurtured, it shows.  If you see a child that hasn't, please don't blame the child.
