Tonight with your 13 to 17 year old
The prompt
“Is there a place you daydream about living or visiting someday?”
What to listen for
Notice what draws them to it, is it the scenery, the pace of life, being near or far from people they know? That detail tells you what kind of life they're imagining for themselves beyond just a location on a map.
If they get animated describing it, let them run with the daydream instead of steering it toward practicality, the value here is in the wanting, not the planning.
If they say "nowhere really," that's fine, you could ask what they'd want more of, wherever they end up, as a softer version of the same question.
What this tells you
This tells you something about the kind of future and freedom they're picturing for themselves, beyond the specifics of geography.
