Dishonest neighbors

Hi, everyone, I made an order and fedex was the carrier, when I checked my tracking number it said it was being delivered on Friday, when the fedex truck stopped at my neighbors house I thought they order something too but at the same time and like hmm that’s weird they never order online and the driver never came into my house I thought maybe another truck is coming so when I checked my tracking number it showed delivered, I saw then picking up the box and took it inside so I thought I should wait to tell them is mine or wait for them to drop it off, well it’s being almost a week and still they haven’t return it to me, I don’t know what to do I know it’s not their fault that the FedEx guy drop it in their house but they knew it was my package and still grabbed it, they’re the type of ppl that never order online because trucks never come to their place, I also have cameras in my house but I don’t want to just say hey I saw in the camera that you have my package, because I want to have a great relationship with them because if I tell them that it’s like an accusing them of stealing which they did not they just got my box by mistake, and the reason I haven’t reported it is because I saw FedEx dropping my package if I hadn’t then things would’ve been different, plus I have other boxes dropped at other house and they always return them to me except this specific neighbors they’re not friendly or even chatty to anyone and am scared to even go and knock on their door, I live in Texas and everyone has a gun and they’re gonna say I was trespassing, anyways I just thought I share this with everyone and hopefully someone else have any similar stories they like to share please do so in the comments thanks for reading, p.s. I still want my package :)
