This is a really hard year for me because it will be so different. On the one hand, I always love getting back into school because I get so tired of our two summer options - either we are on vacation, just getting back from vacation, just getting ready to go on vacation, or we aren't doing anything and everyone sleeps until noon, expects maid and food service, and whines about needing some form of entertainment. So my "school year" routine is much calmer and lets me get much more done in the day.
On the other hand, I'm taking DD17 to college next week, and only DD12 and I will be here!! So it will take some getting used to!!!! Also, I hate homework and projects, and I'm holding my breath about 7th grade and middle school girls. We had some bad years in elementary school, but it was relatively calm last year, surprisingly. So I always have to see if it's going to be a calm year or a dramatic, tears in carpool kind of year.
Also, I HATE packing school lunches - I went to the grocery store last night, and it all came flooding back to me - the Baggies, the little Tupperware containers, choosing something I thought was surefire and having it come home wasted (and spoiled because it sat out all day and can't be recooled.)
So I'll vote for both - I love summer for a lot of reasons and I love the school year for a lot of other reasons!!!!
