Here are some questions commonly used when receiving mail.

"What happens if I am not home and something is delivered to me?"
"Do I need to sign for a package when it comes?"
"If I am out of town can I put a hold on my mail?"
"Can a neighbor accept a package for me?"
"What if I receive a package that is not addressed to me?"

If you are asked any of these questions, here are ways that you could respond.

"If you are not home the postman will leave you a note.  They may try and deliver it another day or you might have to go to your post office to pick it up."
"Sometimes they will just leave the package on your front doorstep.  If you live in an apartment they might just leave it at the rental office."

"Not all packages need to be signed for."
"If you need to sign for a package and are not home they will not leave it."

"Yes, you can put your mail on hold either by filling out a form at your post office."
"Yes, you can actually do it online.  Just check the post office web site."

"I am not sure.  Maybe you should call the post office."
"I think they can but you have to inform the post office before hand that you will allow it."

"I would take a package not addressed to me to the post office and let them know."
"If it was addressed to a neighbor, I would just take it to their house."
