Where I live, we're having a mini heat wave. Apparently, a lot of schools are not equipped to handle this via AC and/or fans, so the kids had a half day. I do understand that it was safer for the kids and for the teachers.
However, this in my mind turned into "In my day, we suffered through the heat and were grateful that PE turned into a mini study hall." I only graduated high school about thirteen years ago and did a mental eye rolling at myself. I also checked my old district and all of the schools were open. Then again, we rarely closed...only time that we closed for real was the blizzard of 2000.
