Help me make up a story to tell my neighbor.

Several months ago, my husband and I came home late to a large package on our doorstep. We brought it into the garage and realized it was not for us—delivery person made a mistake. It was for people on the next street over with the same street number. Since it was late, we planned to bring it over to them the next day.

Never happened. Totally forgot about it.

Just a few days ago, I noticed the package and realized we’d never brought this to the recipient. I looked up the return address to see what it was and found that it was a $375 jewelry press on Etsy.

In the seller’s feedback, “Great, when I finally got it. Thanks for nothing, USPS!”

I’d like to deliver this to the recipient now, but I don’t want to miss out on the person’s reaction to having finally solved this mystery. So I don’t want to just leave it there and run away. I also don’t want to admit to this stranger neighbor that I was at fault for forgetting about this.

So I need a story to explain to the person why I only just discovered this package. Ideas?
