Cornelius.

When the movie opens, a man is just re-emerging into the world after a nervous breakdown caused by the traumatic loss of his wife while his son was just an infant. It's 7 years later, and the man has repressed the memories of his wife's death, and spends his time working a menial job and leaving small gifts on the front porch of the home where his son is now being raised. Eventually, the man and the boy come face to face and, as he and the boy start to bond, the man begins to remember fragments of the buried trauma. While this experience propels him inevitably back to mental trauma, He tries his best to connect with his son in a critical way.
