Final answer:
The author's relationship with his father is loving and close, indicated by the father's affectionate 'cry-smile' and his position as a kind-hearted person in the author's life.
Step-by-step explanation:
The author's relationship with his father could be best described as loving and close. Based on the information provided, the father is characterized as a kind-hearted and loving person, which is demonstrated by his unique 'cry-smile' when experiencing strong positive emotions. This behavior suggests a deep capacity for warmth and affection. Moreover, a loving and close relationship is further supported by research indicating that warm and healthy parent-child relationships are associated with positive child outcomes, and a strong parent-child relationship improves a child's adjustment to situations like divorce. The references to a strong, positive emotion experienced almost daily and the characterization of the father as one of the most kind-hearted and loving people in the author's life affirms a close and emotionally rich bond between them.
