Tonight with your 13 to 17 year old
The prompt
“Is there a tradition from a friend's family that you kind of wish was ours?”
What to listen for
If they share one easily and with enthusiasm, they feel free to admire other families without it being disloyal to ours, which is a healthy, secure way to relate to family life.
If they seem hesitant to say it, reassure them lightly that it's totally fine to like something from elsewhere, this isn't a competition, and you genuinely want to hear it.
Whatever they name, consider it a real, low-stakes suggestion worth actually trying, not just a nice thing to acknowledge and forget.
What this tells you
The tradition they wish we had shows you what they're currently craving more of from family life in general.
