Julie and Jeff are brother and sister; growing up together they are inseparable, going everywhere together. But then Julie gets to an age where she wants to go on dates with boys, not a brother. Jeff does not take well to Julie’s choices for dates. He acts like a jealous boyfriend. Right away we readers begin to think there is something wrong with this relationship.
The story ends in what I think, to say the least, is an unusual turn of the plot.
This story also brings out your old Pappy’s advice for young women: do not date a man with a pencil thin-mustache. They are always carousers and con men. Be warned!
