Everyone remembers where they were when they met "The One".
Whether it was a stroll across Portstewart strand, a relaxing afternoon at Castle Ward, or even a terrifying walk across Carrick-a-Rede rope bridge, the memory of the moment when you met the love of your life never fades.
Sara O'Neill (33) is a stylist and illustrator
She lives in Portstewart with her fiance, surfer Al Mennie, and their dog Blyton. She says:
"I'm from Portrush originally and Al lives here, too, but I moved to Belfast about 15 years ago to go to university and that's when he arrived, so we didn't know each other at all at first.
"I moved back to Portrush about 18 months ago and, around this time last year, I had gone for a walk on Portstewart Strand.
"I was walking on the beach and one of my business cards had come out of my bag. They're quite distinctive as they have one of my illustrations of Marie Antoinette on them. The card had fallen into a puddle and the puddle had frozen and Al came upon it and took a photo. At this point, we still hadn't met, he just liked the image.
"Around the same time, I bumped into the sports reporter Graham Little and got chatting. Graham mentioned Al and a couple of days later, I sent him a friend request on Facebook. We started chatting and he sent me the picture he had taken of my frozen business card.
"We kept chatting on Facebook for a couple of months. Then one day I was at my parents house about to go for a walk on the west strand and I told Al I was going down to the beach for a walk and told him he could join me if he liked.
"That beach means quite a lot to us, as it's where Al saw my business card and it's where we met for the first time and we've stuck together ever since.
"Last summer, Al also proposed to me in a candle-lit cave at Ballintoy Harbour. It's a little quieter, so we were less likely to be disturbed."
Kirsty McMurray (41) is co-host of the Downtown Radio breakfast show
She lives in Bangor with her children, Conor (16) and Katie (14), and her fiance, Andy Brisbane. She says:
"I met Andy on Facebook. It was when it was quite new and he heard my voice on the radio and added me as a friend.
"We chatted online for about three months before we plucked up the courage to meet.
"It was nothing fancy. We actually brought our kids, as Andy has a daughter, too. We met on a Saturday afternoon at KFC in Bow Street Mall in Lisburn. Things did get a bit more romantic after that, though, and we started dating properly without the children!
"A couple of years later, we went to the Snow Patrol gig at Ward Park in Bangor in the summer of 2010.
"Ward Park is quite special to me, as I practically grew up next door to it. It's always been part of my life. I've fed the ducks there, played there and walked through it on the way to school.
"The concert was a massive gig. The next thing I knew, Andy was down on one knee.
"It was a real spur of the moment thing. When he asked, the band were playing Chasing Cars and the next song just happened to be Just Say Yes. It wasn't planned, it was just a coincidence.
"It was a really lovely moment and it's one I can still see in my head. Every time we walk through Ward Park we know exactly where it happened.
"It's made a place that's very special to me even more special."
