Tonight with your 13 to 17 year old

The prompt

“What's a phrase or joke that's basically become its own language in this family?”

What to listen for

If they rattle one off easily and laugh telling it, it means they feel like a genuine insider in the family's private culture, not just someone living in the house, that's real belonging.

If they mention one you'd forgotten about, let that be a fun surprise rather than correcting the details, the point is the shared memory, not getting the story exactly right.

If they can't think of one, you could offer one you remember and see if it sparks something else.

What this tells you

This shows you how much shared, private history already exists between them and the rest of the family.
