Band 9: Your neighbor recently complained about the noise coming from your apartment. Write a letter to your neighbor explaining the situation. You should include: - an apology for the disturbance - an explanation of the source of the noise - a suggestion for how to prevent it from happening again.

Dear Sir or Madam,

I am writing to sincerely apologize for the disturbance caused by my late-night party, which may have disrupted your evening.

The gathering was held to welcome my best friend’s return from the United States after nearly two years of studying abroad. As it was a special occasion, I became rather excited and did not realize that the karaoke activities were creating excessive noise.

I fully understand how frustrating this must have been and deeply regret any inconvenience this may have caused you. I take full responsibility for my lack of consideration and sincerely apologize for interfering with your peace. It was never my intention to cause such disturbance.

To prevent this from happening again, I will ensure that future gatherings are kept at a reasonable volume and consider hosting larger events at a different venue.

Thank you for your patience and understanding. Please let me know if there is anything I can do to make up for the inconvenience.

Yours faithfully,
