Tonight with your 13 to 17 year old
The prompt
“Is there a fight with a friend you wish had gone differently?”
What to listen for
If they share it, listen for whether the regret is about what they said, what they didn't say, or how it ended without resolution. That tells you what they're still carrying and whether it's more about guilt or about missing the friendship.
If they seem to want to talk it through, resist offering a fix right away; ask what they wish they'd said or done, and let them arrive at their own next step, even if it's just "I don't know, I wish I'd apologized."
If they'd rather not go there tonight, respect that fully, you can just say you're glad to listen whenever they want to.
What this tells you
This shows you an unresolved thread in their social world, and how much they might still need your support to find peace with it.
