Our Mail Lady

Our mail lady is really sweet. Not only is she really sweet, but she is about 65 years old. I'm just guessing, it's not like we discuss how old we are or anything like that, but she's not young. Anyway, our mailbox is not at our house. It's down the road a ways, and we just stop on our way home, or walk down there on weekends. When we get something too big to fit in the mailbox, she brings it to the house and either gives it to us, or leaves it on the porch. Yesterday afternoon, David, our youngest, walked down to the mailbox. He did this because he spends his days thinking of ways to make our lives as easy as possible. He was also waiting for a package he had ordered. He came back with the mail and one of those tan papers that says there's something the mail lady couldn't deliver, and I can pick it up at the post office. But we were here! What gives? She didn't drive in! What am I, some normal, regular person on some normal, regular route?? I read the note. It says, "Very heavy! Bring a man :)"
