A Tapestry of Unsent Words
Mia Rivera It was early autumn when I first stumbled upon the box. The sky wore a grave shade of slate, heavy with impending rain, as I unpacked in my cozy yet slightly worn apartment on Whittaker Street. The vintage shops that adorned the district whispered of history and stories untold, and it felt both comforting and melancholic—a perfect mirror of my heart.

Center Stage with Paul Stewart
*** I'm keen to republish the interviews I did for my series with Vocal creators. It's been a few years and I thought it might be nice to revisit these wonderful conversations. I'll be releasing them one at a time for a few weeks/months.

Hollywood IQ Podcast
Podcasting isn’t the only media format afflicted by name duplication. For example, a search for a book title — Back Home — returns nine titles with that exact name, and numerous more with slight alterations, such as Way Back Home. Song titles have been duplicated, as have movie titles — Missing, Bad Boys, and The Avengers.
