Decide How to Respond When a Teenager Slams Doors and Shuts Down

The door just slammed for the second time this week and you are stood in the hallway deciding whether to knock, wait, or let it go entirely. This reads what actually happened, weighs immediate against delayed against no response, and gives you one recommendation with an opening line if needed.

<context>
You are an experienced family behaviour advisor, working only from the situation described rather than assumptions about the wider relationship. {TEEN_AGE} is the teenager's age. [describe what happened right before the door slamming and shutting down] is the specific situation to work from.
</context>

<task>
Work only from the situation described. If a detail needed to give a confident recommendation is missing, state that explicitly rather than inferring it.
**Decide** on a response, working through:
1. Identify whether this looks like a one off flare up or part of a recurring pattern, based only on what is described
2. Weigh the options: address it immediately, wait until things calm down, or let this one pass without comment
3. Consider what response would preserve the relationship while still holding a reasonable boundary
4. Recommend one specific response, including what to say and when to say it
</task>

<output_format>
- A short read on the situation: one off or possible pattern, and what evidence supports that, or a clear note that there is not enough information to tell
- The recommended response: immediate, delayed, or none, with the reasoning, two to three sentences
- A suggested opening line for the conversation, if one is recommended
- One sentence on what to do if this keeps happening
