I recently went to see Hope Springs - Meryl Streep excellent as ever (although I now see her as Margaret Thatcher which distracted me slightly!) but the film was touching, poignant and well acted. However, I thought the ending was a bit contrived, albeit provided a 'feel good' factor when the middle aged couple reconnnected with each other and renewed their vows.
Nevertheless, given that the vows are 'until death us do part' and/or otherwise intended to be on a permanent basis, it does seem to me to be somewhat illogical to 'renew' them, in the way you would renew say a car or a washing machine.
Has anyone done this and, if so, why - for example had you broken your vows or did you just feel that you wanted to make a duplicate public (or private) gesture of commitment?
