Is life fair as we grow older ?

As a mother of 5 children most being grown, I do not have huge expectations of my children taking care of me. My children have children they need to attend too, they must work many hours just to put a roof and keep their family stable. The only expectations I have from my children for when I get to the point of not being able to take care of myself, is that they call me weekly and come and see me every other week. It is the "job" of the mother to do everything for their children until they reach a certain age. You talk about social life? Heck most people dont have time for a social life in todays world. It is neccessary for them to work long grueling hours to make emds meet. What right do I have as their mother to take the time away from them parenting their own children. I remember when I was small my mother took in my great grandmother because she could no longer take care of herself this was many years ago when a family could live off of one income. My great grandmother could not go out anywhere which left me with my 3 sisters stranded at home all the time. My mother was always too tired to spend time with us. This went on for 5 years. Daddy did his best but he worked so much. Finally my mother had a nervous breakdown I was 13 years old. How fair was that to all the kids. My mother finally put her in a nursing home which was wonderful with her. We seen her every week! Sure it would be nice if my children were able to take care of me, but I do not expect it. The expectations I have of them is to continue to love me and dont forget I am still here. If I am so dependent on others for everything in my life please put me in a nursing home. If I can live with you and enjoy our family and do things then that is a different story. Just the way I feel!
