"Celery's Got Mail"

I really like the mail. The unique putter of the truck always seems to wake me up and get me on guard for the big delivery. Most of the time all they get in this box is junk; catalogs, ads, and papers. I haven't figured out the mailman thing. Why on some days is the mailman actually a woman? And why do they sit on the other side of the truck? That's weird. Also, when are these people going to get a new mailbox? It's got a broken flag, a broken door, and it's getting kind of rusty.
