that's not an anniversary I'd want to mark with big celebration either.
We saw a glimpse of the generational gaps of those turbulent times: you detect prejudice against 'long-hairs'and against women wearing pants.
I'd have gone back to the room, dropped the "trousers", wrapped a tablecloth around my waist and marched back down there for dinner!!!
What they could have done was to later have another wedding, with sufficient advance planning, during Paris in the Spring or Bali or some equally temperate place.
This would have supplanted the strong negative impressions of the first one with some lovely new, much more pleasant memories.
