S04E08 Cassette Tape

A man comes back to his hometown to celebrate the wedding of an old elementary school friend. Eager to satisfy his family, he shows up a day ahead of time to spend the night at his parents' house. While reminiscing about his unchanged childhood bedroom, he stumbles upon a cassette tape in a desk drawer marked "What Happened Today" and chooses to give it a listen.
