I think every couple should do whatever makes that couple happy. Contrary to many peoples' opinions (including my mother lol), a wedding is about the couple, not about the family/friends. I would never be offended if one of my friends or relatives chose to elope, or have a private or civil ceremony; why would I? It's THEIR wedding and THEIR marriage! Who am I to get miffed about someone else's personal choices?
Now - I do think weddings are a wonderful opportunity to celebrate one of life's most joyous occasions with friends and family. If a couple wants to have a huge bash, great. But if another couple feels more comfortable doing something private or small, that's great too. Some people have very legitimate reasons for eloping or having a private ceremony, such as social anxiety (hello, I can relate, I can't handle a lot of stress), limited finances, in-laws who can't get along, etc.
Every couple should do what pleases them, and everyone else should be happy for them or keep quiet.
A wedding is mostly about the couple, but lets not forget its also about the combining of parts of 2 families and the creation of new nuclear family. Its about marriage which has been the bedrock of human culture for thousands of years.
So its not really unreasonable for someone who's invested a great deal of time and energy raising a son or a daughter to adulthood might be upset when that adult son or daughter goes and forms their own family in a wedding without informing their parents.
Yes you have to do things for yourself and you can't always follow your parents direction. But at the same time as being independent you can't forget to honor your parents or forget the enormous amount of time and energy those parents put into getting you to where you are today.
I'd be highly curious as to how many parents of children who are 18 to 30 would feel about their children eloping. But I'm guessing most of them would be upset.
And honestly for such an important life event as getting married. . . it seems highly odd to try to keep our family AWAY from it. When you graduated from high school or college did you tell your family not to come or to try to keep them from comming?
Why would one do that for a wedding which is far more important of a life event then graduating.
I remember the day I was married (April 10, 2010)
I remember the day I asked my wife to marry me (March 14, 2009)
I remember the day that we first met (August 1, 2008)
My guess is that I'll always remember those dates.
I don't remember the day that I graduated from college, I only know the month. The same with high school, I don't remember the day, just the month.
