Write a friendly email to my neighbor asking them to keep the noise down after 10pm on Weekdays.
Hi Neighbor!

I hope this email finds you well and getting ready for the sunny spring weather. As the days grow longer, I wanted to ask you for a small favor: can you please try to keep the noise down after 10pm on weekdays? to be clear, I'm not suggesting we all live in libraries--just that external parties, loud music, and fireworks cease after 10pm on weekdays. I'm hopeful that 10pm represents a reasonable compromise between those socializing late and those waking up early. Let me know if you disagree and we can try to work out an alternative compromise. And by all means, please let us know if there are special occasions and/or considerations we should understand. Our goal is to maintain this healthy, thriving neighborhood. 

Thank you,

Kevin
