Our wedding was definitely up there, but not for the 'usual' reasons. It was one of the last times that I had all my grandparents in one place, healthy and happy. All my Aunts, Uncles and cousins were there, meaning my Grandparents had all their children and grandchildren in one place at the same time. It was a lovely day, lots to drink, lots of laughing. It's sadly gone a bit downhill since then, but it was a lovely day and we have so many photos of everyone together.
The other time that stands out is mine and DH's last holiday before dd1 was born. I was 25 weeks pregnant, we'd been refunded £1700 by our bank for some mistake they made to do with our mortgage. I wanted to save it for maternity leave, DH convinced me to spend it on one last holiday.
We've had some amazing holidays together, and he found a lovely all inclusive place in Tenerife which would never usually have been our first choice. But it was honestly so perfect. I literally sat on a sunbed in the shade for 7 whole days, I read 8 books, I drank lovely non-alcoholic cocktails and ate so much lovely food.
But we spent that week enjoying each other's company, talking, planning. At the time we didn't realise how much our lives were about to change, and I did think DH was being daft not saving the money. But I'm so glad we went. It was the last carefree, child free holiday we had and I love reminiscing about that holiday.
