One old saying. "Jaisa Karoge Waisa Bharoge". If They way you treat your parents or parent in laws now you will be treated like that when the time come. So act now and change yourself and change the world.
Lots of messages, for against the law and in favor of the law. People have blamed others, but they have forgotten that pointing (blaming) fingers at other is easy then thinking about his/her mistake. If you point one finger to other you are pointing more (3-4) to yourself. Why not do whatever each and every person can do to help places like Vishranthi Charitable Trust . Also you should make sure that the same thing should not happen to you or your wife when you are old or no longer live in this world. Start saving (or invest in pension plan, life insurance etc) for future now. One life live it happy ever after.
