I have never in my recollection- and I was a military kid and I moved around a lot- attended a school that started this late. We got the day off for labor day.... but it wasn't the last day of summer vacation.
I've been in class for 2 weeks already. I'm pretty sure the high school I went to has been in for three.
Edit: Fine. I went to schools run by a bunch of crazies.
new question. Is it possible to highlight multiple things in a text, like control + click can select multiple things in a drop down list? (and control + highlight doesn't work)
