Rather like living in a large apartment building with a centrally located mail center.
Here, we still get mail delivered to the mailbox at the street end of the driveway. If it won't fit in the box, the mail carrier will drop it off on the front porch. Rather a nice convenience, I think.
For anyone who doesn't already know, the driveway is where you park your auto. The parkway is where you drive it about. Don't ask me, I don't make up the words, I just use them. SM: Ocean Springs
