School's out!!

Michael Gove (Education Secretary) seems to be a name cropping up more and more in the news lately.  His current preoccupation is that school hours should be longer and holidays shorter.  He makes the point - quite correctly - that the present school holiday schedule has its origins in the days when we were basically an agricultural society and children were an important part of the manpower needed to get the harvest in - hence the 6-week late-July to early-September holiday.  But really the question is whether that is sufficient reason to change things.  As a grandparent who has grandchildren duties during term time, can I say how much I look forward to six weeks off in the summer?
