It feels lighter
Some of the explanations given for messed-up deliveries of your packages simply cross the line between making sense and not making sense. In this picture, the owner received a package with a giant hole underneath to find out that the package was entirely empty.

How come such a thing even happens? The shipping guy must have been handling the package all through the process and at one point be like, “ oh now it feels lighter.” The recipient must have been left wondering why did they even bother to deliver the empty envelope.
