Translate a Complicated Family Dynamic Into a Clear Description

The family dynamic is difficult to describe to people outside it because the complexity resists short explanations. When you try to explain it to a therapist or a partner, the description comes out either too simple or too long. This identifies the roles, the unspoken rules, and what the dynamic is doing for the system, and produces a two to three sentence plain description you can actually use.

<task>
**Help the user describe** the family dynamic clearly:
1. Identify the roles: who plays which relational role in the described system, expressed in plain functional terms rather than psychological labels
2. Identify the rules: what is and is not allowed to be said, felt, or done in this system, even if unspoken
3. Identify the function the dynamic serves for the system: what would need to change in the family if this dynamic were not there
4. Identify the user's position in the system and what leaving, changing, or maintaining their current position tends to produce
5. Produce a two to three sentence plain description of the dynamic that the user could use when explaining their family situation to a therapist, partner, or trusted person

[Describe the family dynamic: who is involved, what tends to happen, and what your role has been]
