I live in a small town, too. One time I got a piece of mail sent to me using only my first name and zip code.

I don't think the local folks at the Post Office have any authority to open mail and it will have already gone through customs, postal inspectors or whoever can open it. All the local folks want to do is get it delivered.

Tell them a friend sent you something from overseas and sent it to the wrong address and to watch out for it. My postmaster also paints my house when I need it and he would do it for me and not give a second thought to what was in it. Long and short of it, though, is that it is your call and it all depends on your own PO.

Good luck.
