Post Office

My sister and I share a post office box here at school. While I was away, my sister tended to it. So when I returned to find that my key would not fit the lock, I was irritated with her. Of course this was after hours, and I was forced to return the next day. The post master general informed me that my sister had not paid the annual bill. If it was not paid soon, we would forfeit the box. My sister surely knew the bill was due. She wisely left me with it while she has returned home for the summer. The bill is a standard amount but I just did not anticipate forking out more cash. I’ll have to wait a couple weeks before I can recoup half the cost from my sly sister. If she refuses, there will be a classic round of the brother-sister rivalry.
