Write a LinkedIn post from a client story

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

Context: The stories with pull come from real matters, which is the difficulty. Tell the situation and the lesson, and change or drop anything that points to a person.

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 legal information only. Never write anything that reads as advice on a person's own situation, and never suggest 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 the partner who approves marketing should see:
- That no client, opponent or matter can be identified
- Anything that reads as a comment on live proceedings
- The fee earner's agreement to the post
