Interesting weekend read on the presence and purpose of parents in the school environment, specifically at mealtime.
"The grade-school lunchroom has long acted as a microcosm of social life. It’s where kids choose whom to sit with, develop friendships, and resolve conflicts. And lunch is one of the few less-supervised periods in most kids’ school days. Over the past several years, however, some school cafeterias have become invaded by a new group: parents." http://ow.ly/Z8Jd30mQsc7
