This Package Inside the P.O. Box
A P.O. Box or post office box is an addressable lockable box located inside the post office that people can visit to retrieve their mail. But this person was very surprised to find that a package had managed to fit so perfectly inside their post office box. Unfortunately, it fit a little too well and got pushed all the way to the far back. So, this person probably had a hard time getting their package out. Hopefully they had long arms.
