Affection is a word that cant be used singularly. It always come in unison with another or in a group. In a family we see affection for parents, siblings, cousins...and for family friends too.
Having understood the above let us look at the topic of Kids affection for their parents against affection for their respective life partners.
Are both kinds of affection needed for the child ?? yes, they need parents and they need life partner...can one replace the other - NO !!
So why is that a boy or girl is asked to make a choice when they find a life partner for themselves??( In reality from our younger age we have always been asked to choose betwn family members ) To answer this question, we need to look at certain aspects of culture.
When a child is small and we have guest at home...the first thing they will ask is do you like ur mom or ur dad more??/ or do you like your parents or grandparents more?? And these elders they wait eagerly to hear the answer from the child and rejoice when he/she/they become the chosen one... is it right to rejoice - my answer is NO!! I have found this the most irritating thing that is been asked to a child. To choose among the family members. How can you take a member out of the family and make them more imp. A family is complete with every individual in the family . So why choose??
Its like asking which part of the body can you throw or replace for the other. We need every part to complete the body and to make it fully functional. In the same way every individual in the family is important for the child to grow up and be the man/woman . Each family mem contribute to the development and growth of the child into adulthood.
Now getting back to the Son - Mom - DIL issue.
Boys in India are more like investments because they are going to take care of their parents and responsibility of the house and be the "PROVIDER". And from younger age it is drilled into their brain that their parents have invested a lot on them as they are going to be the back bone and support during parents old age. This ( their parents have invested a lot on them )stays with them and as they grow up they find it difficult to go against parents.
Girls from younger age is taught to sacrifice and adjust . Always drilled into their brain that they need to get married and go to some other house where they need to adjust and sacrifice their needs for the family. Parents knowing this learn to accept that their daughter is going to leave them one day so the acceptance of that truth ( letting free) happens early.
In short boys are made to look like providers and girls as home makers. So when the Son brings a girl home as his life partner, his parents have this thought that they will have to share their son ( and his wealth ) with this new girl who is not even family. Their thought is how could he do this because this new person didn't invest anything on him. Its they who have taken the pain of bringing him up and now there is need to share him and everything abt him !! . Girl will keep quiet because she has been taught to do that (sacrifice and adjust) .
So if we need a change then we need to change. We should bring both boys and girls with a sense of balance. Money is important both should be taught to earn. Adjustments and sacrifices are not meant for women alone . It has to be done by both . Above all as they grow up allow them to take decisions and start taking a back seat when it comes to their choices in life. Once they reach the adulthood Guide them but never decide for them . Then you will see that the percentage of boys and girls learning to stand up for their needs will be more.
Always remember children are given to us to bring them up . So that we can teach them to survive in this world. We shouldn't treat them as investments and hope for a better return of investment later in life.
As far as taking care of old people and people not well at home. It is every ones responsibility in the family not just of sons.
