Ordering Amazon from the Great Beyond

On the way home from work, I saw something interesting.  What does it mean if you see a UPS truck leaving the cemetery?  You know they're not making a delivery.  They certainly aren't going to get anyone to sign for it.  

I don't want to see it if they do.

One has to assume they were visiting the grave of a loved one, or something like that.  Maybe somebody has trouble with addresses.  Either that, or UPS has delivery service to the grave.
