From a post about excessive amounts of homework (boldface mine):
Every parent I know in New York City comments on how much homework their children have. These lamentations are a ritual whenever we are gathered around kitchen islands talking about our kids’ schools.
Is it too much?
Well, imagine if after putting in a full day at the office—and school is pretty much what our children do for a job—you had to come home and do another four or so hours of office work. Monday through Friday. Plus Esmee gets homework every weekend. If your job required that kind of work after work, how long would you last?
(Personally, I went to a school with lots of homework. I became really good at doing it on the bus. I’m not sure how much I learned by doing that however).
