I put the wrong answer on this before and I'm not sure what the correct one is or how to completely delete this comment so I'm sorry to anyone looking for the answer.
I believe the answer is: Moderate income families
High income family tend to pampered their children and made them obtain what they want without making the effort while low income family tend to pay less attention to their children since they are trying to fulfill ends' meet.
Moderate income familiest end to has sufficient time to take care of their children and have enough money to fulfill their needs without pampering them.
Answer: View of common sense of ones obligations/duty towards other people.
Explanation:
According to the theory of utilitarians, increasing the happiness and right actions should be done for the affected or suffering person. As a duty of a person towards their close ones, he/she should create the atmosphere of well being by acknowledging the interest of other people.
According to the situation mentioned in question, an individual doing party on the basis of obligation to create happiness for his/her grandmother instead of meeting her at her dying stage indicates view of common sense of performing duty for suffering people in terms of utilitarians.
