It is sickening to see the criminal negligence and rank irresponsibility shown by ungrateful sons/daughters,who forget the same may be waiting for them.In the same way had their parents thrown them when they were young,what would have been their fate.what Mrs.vaithi doing is great!But it also gives room for people to get rid of their parents/elders,having come to know that some place there,where they can offload their unwanted folks.I feel we must make these wretched folks realise this animal behavior by some coercive methods so that the parents are taken better care at their place itself.For,no place can replace one's own house.
