emotional blackmailing...
You call it emotional blackmailing, but there are core family values which are dear to us.
Otherwise what is difference between marrying to gories, i am bringing a brown gori instead of white one?
We have done this for our parent till their last breaths, what is wrong expecting same with your own child?
I have 3 daughters, i can tell you it is my expectation from them to be good DIL, willing to take responsibility for their husband families.
Thanks god despite living out side Pakistan, Allah blessed them of both worlds as they are have a modern outlook, as well as very much family oriented person.
On other side if my son want to bring a selfish girl (a brown gori), who is or not willing to see beyond her own life then good luck to him.
