I always remember my first cold water dive. It was in Aberdeen, Scotland in February and its was absolutely Goddamned freezing, and I was wearing an ill fitting borrowed wetsuit. Very low viz. Nothing to look at except rocks and seaweed. After the dive we had to clamber up the rocks and cross a field of sheep in our gear to get back to the car park. When we got there, we came across another group of divers gearing up. And the whole time whilst we are stripping down and they are gearing up, I could not stop grinning.
Eventually one of them asks me, "so why are you grinning like that?"
"Because you still have to do it!" I replied with a smile.
