My view is not involved, not against, all depends on the old man to make their own decision . The young people get married, there are still work problems, economic problems, geographical problems, the two parents of the old age problem and so on. The old man remarried, the resistance suffered than the young man's to be too much, which is the main problem is the property belonging to the problem, the old man's disease problem, both children and step-parents get along with the problem and both children get along with the problem between.
We should put all the possible problems on the table before the old man remarries, and discuss how to deal with them properly if something like this happens in the future, in a way that is acceptable to all. Then, if there are really unexpected problems after remarriage, there shouldn't be too much resentment. That said, human nature is selfish, and anyone who wants their children to do well will consciously or unconsciously favor their children. This is in fact no excuse, parents of their own children have relatives near and far, let alone with their own stepchildren have no blood relations.
Again, children and filial piety can not be accompanied by parents every day, the elderly widowed is very lonely, especially in the dead of night, full of children and grandchildren as old as the companion, the old companion old companion, that is, when the old companion, parents remarried, the heart of the sadness, is not a good thing? Elderly people's property is his own, want to how to spend want to whom to spend is his own right, we will not intervene, and, their own filial piety parents of the money will not be less.
Finally, we and our step-parents' children follow the general pattern of friends, and do not have too much contact with each other, so as not to cause unnecessary trouble and misunderstanding. The last is the problem of disease, our own parents are sick we manage, will not ask each other to take responsibility, step parents are sick we will also contribute to the appropriate medical expenses, and care, do a good job of the children's work. I think if you follow this idea and set your mind right, there is nothing wrong with your parents remarrying,of course, provided they are healthy and willing to remarry.
