Till Death Do We Volley - S4-E19
Corrected entry: Dorothy's friend Trudy comes to Miami for their high school reunion when there is no possible way for Dorothy to have gone to high school in Miami. It would have been in Brooklyn. In so many flashbacks she is way older than a college student, and they still live in NY.
Correction: There is no reason a reunion can't be out of town; schools often do multiple reunion activities in various locations. In this case, Florida is a very popular destination for Northeastern retirees, so there certainly could be enough high school alumni living in Florida to justify a reunion activity there. All an alum would have to do is organize one.
