redhelen, i really disagree with your opinion that it's a generational thing. that might be true of someone in their 80s but i really believe that many older people really couldn't care, i think it's more to do with a persons attitude than age. i know a number of people whose grandchildren live with their partners and have children but who aren't married and really these grandparents don't give a toss. 'oldies' are far more tolerant than they're given credit for.
conversely, some of my contemporaries are pushing or have pushed their children into the whole white wedding thing, spending fortunes on 'the day', the brides mothers outfit, the 'venue', goodness knows what else. and at least 3 of these have already ended in divorce with money still being owed.
