The birth of resentment

Sam hung up the phone, the soft *click* echoing in the silence of the room. His mind was a swirling mass of thoughts, memories, and desires that seemed to tangle into one another. The weight of the past bore down on him, especially the events of three years ago. Those memories were the foundation of the path he had chosen, the fuel for his determination, and the source of his deepest resentments. The recollections tugged at him, pulling him into a daydream.

Three years ago had been the breaking point.
