Your new neighbours have recently invited you to a party they are holding next Saturday. However, you have other plans on Saturday evening and cannot attend the party.

Dear Neighbours,

Thank you so much for the kind invitation to your party next Saturday. I truly appreciate the gesture and am grateful to have such friendly neighbours like you. It means a lot to me to be included in your celebration.

Unfortunately, I already have plans for Saturday evening that I cannot change. I have a prior commitment with some friends that I made a while ago. I hope you understand and that we can catch up another time.

I would love to meet up with you both outside of the party. Perhaps we could arrange to have coffee or dinner together next weekend? I am available on Sunday afternoon if that works for you. It would be great to get to know you better in a more intimate setting.

Looking forward to connecting with you soon.

Best regards, [Your Name]
