Write a LinkedIn post from a client story

I work in marketing at a financial advice firm. Help me write a LinkedIn post from something that happened at work.

Context: The best stories come from client meetings, where the detail is private. Advisers often post from personal profiles, and those posts still get read as the firm speaking.

Before you start, ask me for anything missing from this list:
- What happened, in rough notes
- The point I want to make
- What I must leave out

Then:
1. Find the one idea.
2. Open with a specific moment or fact.
3. Keep paragraphs to one to three lines.
4. End on the point or one next step.

Give me:
- The post, 80 to 200 words
- An alternative first line

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general financial information only. Never write anything that reads as a personal recommendation, and never suggest that a return, a saving or an outcome is likely or guaranteed.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else our compliance officer or whoever approves our financial promotions should see:
- That no client or family can be identified from the story
- Whether this post needs approval before the adviser publishes it
- Any outcome or figure in the story that implies a typical result
