The Sea: It's big and cold and everything in it hates you

I love the sea. I love living by the sea. I love the smell of salt on the air and sound of crashing waves, I love harbours and beaches and gulls and pretty much everything else about being near the sea. I am not, however, crazy keen about being in the sea. I'm intensely aware that I am a land creature and not well suited to submarine life. I'm slow and cumbersome in the water and it's not my favoured medium for breathing. There are things in the sea which are much better adapted than me, strange alien creatures, cold unfeeling things that circling incomprehensible depths, huge fearsome behemoths that dwarf anything found on the land. They live there, it's their home and you're not welcome....
