I think there should be some changes in “property law" in Nepal. If you acquire property that is not inherited should have no right to son or daughter other than wife. Even to wife only half of it will go to her. 

Once we change, different thought will merge in young generation. No more dependent of Parents and no law suite against parents. I work had and made my life, I must have my way to live and use property.

It will change the concept of life and living style. Then you can have somebody help you or sell the property and enjoy the way you want.
