The aroma of freshly brewed coffee filled the air as David sat at his desk, sorting through old paperwork. A flash of familiar script caught his eye: a letter he had once written. It was a note to his son, who was away at college.

He closed his eyes for a moment, letting the warmth of the coffee seep into his bones. His heart pounded in his chest as he began to read. The words were filled with hope and dreams, expressing a deep love. He felt an intense connection to the words, as a feeling of bliss bloomed within him. He felt as though he could conquer anything.
