Your teenager is quieter. Their sleep has changed. Conversations are shorter. Every item on that list also describes a perfectly normal fifteen-year-old, which is why parents explain it away. Chris Coulter on the difference between teenage moodiness and something worth attention, the six questions that separate a bad week from a pattern, and why knowing your child's baseline matters more than knowing the warning signs.

Boys rarely say they're sad. They go short, retreat to their room, and answer everything with "I'm fine." Most parents read that as normal teenage behaviour, and most of the time they're right. Sometimes it's grief with no language attached. A father writes about why attitude is often the only signal a boy can send, and what to do when you're already noticing something.

Chris Coulter thought he knew his daughter better than anyone. A quiet four-hour drive home from Prince Edward Island proved him wrong in ways he wouldn't understand for years. This piece looks at confirmation bias in parenting, why "fine" isn't proof of anything, and the early warning signs of teen depression that get explained away. For parents who assume they'd know if something was wrong.
