The girls are growing up! Laura and Nellie are heading towards adulthood at a high rate of speed and there are many changes in store.
Nellie takes the graduation exam, which she passes, meaning that she is no longer a student. The town welcomes a new teacher, Eliza Jane Wilder, who is an older woman with a younger brother named Almanzo who is destined to be Laura's future husband. (In spite of Nellie's best efforts to have him attracted to her!)
Meanwhile, Harriet gives Nellie a rather ostentatious graduation present - her very own restaurant, named "Nellie's", which offers food and accomodation and which, apparently, Nellie and Harriet intend to run between them. Such a pity for the patrons that neither of them can cook to save themselves!
When Charles is injured and unable to work temporarily, Caroline, much to his annoyance, takes a job as cook in the new restaurant which is probably a good thing as the townsfolk seem very disinclined to eat the earlier offerings.
A wonderful episode and a great way to introduce the Wilder family to the series. You must watch this one!
