[N-Da-Ring]

I'm a mailman. So I my be able to help you. What was the reason for the return(it being returned to you)? It will either have some letters on the side of the address you sent it to or will have the reason why it was returned. For example IA-insuffencient address, ANK- Attempted not known, NSN-no such number, NMR- no mail receptical, and so forth. And by the way after you correct the mistake or whatever the problem is if you leave it in the same package you won't have to pay again to mail it. Was it sent where he had to sign for it? If so then that may be why it was returned. Because if he wasn't home when they tried to deliever it then a pink notice should have been left in his box telling him to pick up the package. He has so many days to pick it up from the PO after that time is up then they return to sender. Hopefully this helps.
