Do you know who the best people in the world are? They're the ones who "get" your kid. The ones who believe in her and have high expectations for her, but who step in with grace and affection and love when the kid gets overwhelmed, or makes an honest mistake, or even does something boneheaded.
They're the ones who give you room to laugh and shake your head and remember that we were all once just-barely-grown and trying to figure it all out.
They allow you to shed your frustration and come back to a place of support and encouragement.
They're the ones who point out what they love about your child when your brain is freaking out and you're starting to wonder if the only real options available are homelessness or living in the basement. (Which, they're not. But the brain is a crazy organ with a warped sense of humor.)
They're the ones who willingly write up a letter of recommendation on only 12 hours notice because someone didn't read the application all the way to the end before taking a deep, panicked breath and starting on the essay.
They're the ones who share their own stories with your child -- about missed deadlines, or botched labs, or fender benders, or whatever mishap your own kid is currently beating herself about the head for. (We actually spent about half an hour at book club a couple of weeks ago sharing stories of freak car incidents we'd all experienced, to encourage a young man who'd had One Of Those Days. In the end, he was able to laugh - mostly at us, and our ridiculous stories - and realize that he hadn't doomed himself to being That Kid forever and ever.)
They laugh gently, they cluck sympathetically, they point out that it doesn't mean you're awful, it means you're human.
And humans are fantastic if you give them room to be!
The best way to find these people is to be one of these people. If you have this, feed it regularly and roll around in it - you're all doing good work, and it matters. If you don't have this, fire it up. Roll up your sleeves and go love on some kids. You'll find your people. They tend to create a symbiotic energy, encouraging and loving on each other and each other's children in turn. It's a beautiful gift you can give to yourself, your children, your friends, their children, and so on. It really is.
