I recommended them a day or two ago. I don't get six weeks at a time as I am not teaching (I only get six weeks all year) but I have come to appreciate that it can be daunting for some to have so much time off in one stretch (it appears to be the younger ones! That is not intended as a gripe!) What did you do as a student, when you had 3 months off? My time was always filled - of course, most of my friends were free too, that is not necessarily the case when you are working and your friends are not also teachers.
