My babies are starting HS in a couple of weeks (have 2 in college and a junior in HS). They will be playing soccer. Dd is still in tryouts, ds will be playing on the freshman team, but will play up on varsity (they only allow one freshman on varsity, he was #2, our JV coach is horrible, the freshman team beats JV in scrimmages). They are taking all honors classes and physics, not sure how that will go. They've always been in mostly the same classes (middle school had the kids in groups, and both were in choir and geometry, so had to be in the same group), but I know they separate twins more in HS. They get along pretty well, at least to the extent that many don't know they are twins. Dd is a lot more organized than ds, so I'm losing my safety net if they have a lot of different teachers, but both DH and I attended the same HS as our kids, and we are good friends with the principal (one of DH's best friends since elementary school), so there is a high comfort level for us.
HS years go by in a blink!
