The title says it all really...
On one fine day, we took the chance to go swimming with wild dolphins off Kaikoura, a town on the north-east coast of New Zealand's South Island. It's an unusual area because an ocean trench comes right up to the coast, which means whales, dolphins and all manner of deep-water animals are regularly seen just off-shore.
So under a beautiful blue, white and silver sky we set off on our boat into the bay - trussed up in wet suits, goggles, flippers and snorkels - ready for our hoped-for encounter with the local Dusky dolphins.
And it wasn't long before we found ourselves sitting on the back of the boat, feet trailing in the water and mouths hanging open as we spotted a 200-strong pod of dolphins moving together at fair speed but also breaching and leaping out of the water. Our boat manoeuvered ahead of the pod, and off we leapt.
Now to be honest, the first group took little notice of us. In fact they cut through our 12-strong group like a knife through butter, and in just a few moments they were all gone. We all felt a little disappointed, and a little like dolphin roadkill.
But after a brief few minutes back on board, we caught up with the same group and we tried again. And when I say tried, there is actually an art to this strange adventure. The thing is, the quite correct ethic of the trip is that if you want the dolphins to stop and take an interest in you, you must remember that you're there to entertain the dolphin, not the other way around.
I'd never thought about how to amuse a dolphin before, but thankfully you do get a good briefing beforehand. The simple version includes duck-diving down into the water, as possible as that is in a buoyant wetsuit, frantically trying to mirror the curious mammals when they circle you at close quarters and, best of all, humming, singing or making interesting noises.
So despite the fact that 12 grown adults were dressed head to toe in rubber, bobbing around like corks in open sea and all the while yelping and squawking... everybody enjoyed one of the most special experiences of their lives.
Although the time passed in a flash, we had more than 45 minutes during which many of the pod decided we merited further inspection, swimming right up and around us, circling and weaving in and out usually at high speed. But they also put on a show, leaping right out of the water with forward rolls, back flips, and all manner of acrobatics that were an absolute joy to behold. I was so engrossed in all of this that I almost forgot to pick up the camera - but this is certainly one experience when the memories will be more vivid than any photograph.
