I have to admit I very much enjoyed my fancy wedding. It wasn't my idea from the start, more something to keep my mother happy as her only daughter was moving abroad (she paid). But I thoroughly enjoyed it for lots of reasons:
it did keep my mother happy, which would be a big consideration with me at any time
we had to get married anyway (rather than just live together) for immigration reasons
it seemed the worthy celebration of a 10 year long engagement, when we hadn't even been able to live in the same country
it was very much a change of life for me: having just finished my PdD, leaving all my friends, starting life in a new country- it felt appropriate to mark that with something big
it was a great opportunity to gather and review the extended family (gosh, he's grown up to look just like his great-aunt!)
it was a great opportunity to squeeze members of both families under one roof and introduce them to each other
the food was good- and I'm a greedy pig!
growing up in the 70's (the Abba decade) I haven't exactly been overrun with opportunities to dance the waltz- and I've always wanted to
it was a chance to say goodbye and thank you to my friends
also a chance for my parents to invite and introduce some of their old friends
it's one more incentive to stick together- can't let a wedding like that go to waste
And yes, 15 years later (that is, 25 years later in the relationship) we are still together and I expect we will stay together 'until death us do part'.
