Something serious is happening — to you or to someone you know. Maybe a kid is being badly bullied, or someone's being pressured into something dangerous, or there's a situation that's gone beyond what kids can handle. You know, deep down, that an adult needs to be told. But there's a powerful pull not to: the fear of being called a grass, of making it worse, of getting someone in trouble, of being the one who "told." So you're stuck, weighing a rule you've absorbed — don't tell on people — against a feeling that's getting louder: that this is too big, too serious, to keep handling on your own.
