Final answer:
The father in "Once Upon a Time" shows a change by considering adopting a more traditional lifestyle with less dependence on technology to reconnect with his family.
Step-by-step explanation:
One specific way the father has changed in "Once Upon a Time" is by becoming more open to the idea of a less technology-dependent lifestyle.
This change is evident when he considers turning off the high-tech house to live a "sort of a happy family existence."
Initially, it seems that conveniences and machines defined the family's way of life, but the father's shift in perspective, emphasizing manual activities such as painting, tying shoes, and brushing teeth, suggests a yearning for a more traditional, hands-on approach to living.
This change may be motivated by a desire to reconnect with his son and reestablish family dynamics that have been disrupted by an over-reliance on technology.
