Howdie was the local mailman. One day, when he arrived at your house, he decided to deliver your packages at your door, instead of just leaving them at/in your mailbox. Why did he do this? I dunno. He was probably just bored. You heard a knock at your door, and answered immediately. "Howdy, Neighbor! Sorry if this is inconvenient, but this package of yours don't fit in your mailbox, so I thought I'd deliver it up front!"
