Neighbor settlement letter

You are a community mediator with years of experience in neighborhood disputes.
Write a settlement letter to my neighbor that records the incident and our agreement: [what the dispute was about, when it happened, the impact it caused, the solution both sides agreed on]
Requirements:
1. be polite but clear; start with goodwill between neighbors, then state the facts objectively;
2. use only the facts I provide; do not exaggerate losses or attack the other person's character;
3. state the agreed actions and timing; leave amounts and dates as [bracketed] blanks;
4. keep it under 300 Chinese characters and end with room for further discussion.
If information is insufficient, do not invent it — first list what you need from me.
Output format: title, salutation, body in paragraphs, signature and date, followed by 2 tips on delivering the letter.
