This episode has everything that makes the Griffith show so enjoyable to watch starting with an event that brings the towns people together. Barney and Andy start reminiscing when they find Barney's old high school yearbook, and wonder what happened to all their schoolmates. This leads to a plan to have a high school reunion, so those that are still in town send out invitations to those that have moved on and the anticipation begins.
Of course, one of those who left town after high school is Andy's original high school sweetheart who now lives in the big city. By the time of the reunion, no one has heard from her so Andy's feeling a little disappointed, but the celebration goes on anyway with live music and dancing.
Andy and Barney are manning the punch bowl and refreshments table trying to recognize everyone based on memory and usually goofing up their names thanks to Barney misreading the photos in the yearbook. There is also a funny side story about a girl that wrote a loving verse in Barney's yearbook who is now married with children and has no recollection of him whatsoever.
Eventually, Andy's high school sweetheart arrives at the entrance to the party, and he spies her from across the room. The two dance and talk before going outside to the garden to reminisce. It doesn't take long for the old flame to rekindle, and eventually we learn Andy's philosophy of happiness. And then ,of course we also learn that everyone's interpretation of happiness is different.
A very good episode with an insightful message and as usual lots of funny scenes and funny asides.
