Reason one: some people are just mean.
Well yeah, people are always going to be jerks. People are always going to say and do cruel things with the intention to hurt you. And they will hurt you, seemingly with relish. The old sayings tell you to kill 'em with kindness, that honey catches more flies. Sometimes, though, honey doesn't work, and reflexively you reach for the flyswatter. You and everybody else that kid has dealt with for the last sixteen years. All you can really do is not let it phase you, roll with the punches. Don't blink. What a shock to have those blows casually ignored. Sometimes enough of a shock to challenge a belief, and enough times and you may start to see a shift in behavior. Not always, not every day. But maybe.
Reason two: some people are just lazy
This one gets me. I hear my staff and faculty toss it around like it's something a kid actively participates in, like an extracurricular. I was a smart, capable kid. I was engaged. And damn was I lazy. It's so easy to forget how hard it is to be a teenager. Increasing responsibilities, plus all those hormones? It's only natural to shut down, or to do the bare minimum. To avoid. To hide. To complain. That was me. Hell, that's still me sometimes, and most people would agree that I did all right (in high school and since). The primary difference? My kids here at school have a fraction of the support I did. How can I abandon them too?
Reason three: Some people can't be fixed.
This is true, but not the way you might think. It's a fact of life. People will always think there is something inherently wrong with others. People who are different need to be fixed. People who are this or that, people who are angry or lazy, something is wrong with them. No. Something is wrong with you, me, the system, the world, that a kid can grow up with so much hate in her heart or so much weight on his shoulders. What's wrong is me, thinking I can change them. They may be broken, but that doesn't mean there is something wrong with them. There is so much right that I've been privileged to see this year. The angry girl channeling her aggression to challenge an injustice; the frustrated boy sticking with it, his pain visible, exposed by a simple algebraic equation; the spaz with a heart of gold showing me what it means to live in the moment (consequences be damned). There is nothing wrong with these kids except that they've always been told that there's something wrong with them. And I've told them that too, in my own moments of frustration, in my own moments of anger. And for that, I feel a deep sadness. Could I have done better, acted differently when faced with challenges, earned their trust, their respect? Probably. But in this moment, feeling pretty vulnerable as I mentally prepare for my last day, I can't change the past, I can't think about the things about myself that I want to fix. Because there's nothing wrong with me either.
