It seems a bad move to take unfilial children to the Tribunal for the Maintenance of Parents because it would strain ties further ("Parent maintenance cases 'often down to strained ties' "; Dec 6).

Education needs to be boosted, most essentially from the primary school level, on the need for children, when they grow up, to maintain their elderly parents.

When adult children do not show gratitude to their parents in the form of maintenance, the governments of many countries will have to step in, something that is unsustainable in the long run.

In the past, we cared for our aged parents, no questions asked, but it seems like society is now changing.
