Insensitive Hag.

Are you someone's child, or someone's spouse?
When you get married, you have to make a conscious decision to become "family" to the person to whom you read your vows. I understand that you will never stop being someone's son or daughter. But at some point (hopefully, very early in the marriage) you need to decide who you're going to pledge allegiance to if the time should come. Who is your first priority?
In my opinion, your parents have already lived their lives. They got their chance to have a spouse and raise a family, start their own traditions, make their own choices, and enjoy some privacy. So when it comes time for their offspring to take that path, in my opinion, it is not fair of them to ask their children to put life on hold. It's not fair to their spouses. Now nobody has a chance.
Perhaps I am an insensitive hag for thinking this. I have yet to be in this position with my own parents, so I speak from a removed view of the situation. But maybe that is the most rational.
