Sigh. It sucks that almost daily, I say a brief prayer (and I'm not overly religious) something like this, "Please, let my students be safe today." Some days or weeks, you can feel the different tension in the building and wonder "is today the day?"
I'm not trying to make any excuses - we don't know anything about this kid. And that's my approach every day. Even though they're in high school now, they're still just kids, trying to figure things out. Much like the rest of us, without the experience or wisdom we've gained from trying to figure things out. All that said, I feel bad for this kid that somewhere, somehow, we've done a disservice. While at the same time, I feel for the students and teachers that are hurting and scared today. And finally, as a parent myself, I can't imagine what they're going through. Sigh.
