Actually, it is a fair question. It exposes the potential for children to take advantage of their parents good will. Dipping into Super is quite different to helping out with cash savings.... the compounding attrition could be huge.
I've already allocated funds for my son to attend Uni or Trade school or whatever he chooses. But he will pay it back.... then when it is paid back, I will gift it to him as an investment or deposit on a house. But it won't be coming out of any super account, even if it was an option.
It was an intrusive, personal, none of anyone's business question whether the poster had to pay their mother back or not. The poster didn't suggest others do the same, they just explained what happened in their family.
