Our neighbours are wonderful. They're very kind and helpful, not to mention generous! We let them know we were having a small get together for my partners 30th a few months ago, and that there could be some noise, and they could join us if they wanted. They chose not to join, but sent a gift. It was so kind and thoughtful!
We haven't known them very long, but they mentioned in passing that they're getting married in a few weeks. Would it be weird to get them a wedding gift? We were going to drop it in the night before their wedding so that they don't feel like they need to offer us an invite.
