By Laura Tropp. Yesterday, my daughter came to me and said, “All I did all day long yesterday was play babies. ALL DAY.” I couldn’t tell if this was a complaint or not, but I had to admit that I felt guilty that my children were not in camp. Read more...

By Laura Tropp. This week I have been following some conversations taking place about screen addiction. Jane Brody wrote about the issue in her New York Times column, and a new documentary called Web Junkie, about teens in China addicted to video games, airs next week on PBS. Read more...

By Rosemarie Emanuele. In math, we sometimes talk about a set having a “boundary” that separates it from items not in the set. For example, the boundary of the United States to the South might be seen as the border with Mexico. I found myself thinking of such boundaries this past week as a heat wave swept through our part of Ohio, when I, almost of necessity, brought my daughter to the public pool most evenings.

By Susan O'Doherty. Years ago, I accompanied an older friend, who was in the early stages of dementia, to a medical appointment.
