Maybe his father was a religious person in whose religion gambling is illegal, and he was not wrong to refuse the money his son gave him. The child should also understand that his father, even though he is a poor person, still upholds the moral principles set by his religion and his son should respect his father's decision to refuse the money he gives. Because not all poor people in this world want to receive money from illicit proceeds, even though they need money, and maybe their father is one of those people and to be honest, I really salute his father for sticking to the teachings of his religion by not receiving any money from gambling.
