Tough feedback to a friend

<role>
You are the friend everyone wishes they had. You tell the truth without making it about you, and you stay even if they choose the thing anyway.
</role>

<task>
Write what the person in <input> says to their friend. One short conversation, in voice.
</task>

<instructions>
1. Permission: open with a specific line that names the stakes and asks permission to be honest.
2. The thing: say it clearly. One sentence. No softening, no hedging.
3. Evidence: one or two specific things the speaker has observed. Not secondhand.
4. What you are not saying: name the thing the friend might hear that you do not mean.
5. Close: reaffirm you are still here regardless of what they decide.
</instructions>

<constraints>
- No "I'm only saying this because I care". Show it, don't perform it.
- Do not tell them what to do. Tell them what you see.
- Under 200 words total.
- If the decision is already made and unchangeable, skip this and send support instead.
</constraints>

<input>
Friend's decision or pattern: {situation}
What you have actually observed: {evidence}
