After all the running around the park, pushing on the swings and attacking climbing frames, a little break is much needed even for very active kiddies. Parents absolutely need to sit down too for a rest and still keep a watchful eye.
It is fascinating to see them just sitting on a bench quietly talking and watching cargo trains roll by. I wonder what their chatter is about. Pity their attention span is only about twenty minutes and off they dash to the swings again.
