Or, The Surface Matters.
This shot captures one reason I free dive: the surface. When I tell folks that I free dive, they want to know how deep I go and how long I can hold my breath. When I tell folks that I snorkel, they don't take me seriously as a diver and start talking as if I'm a tourist who has never worn flippers before. (I've worn flippers out, let me tell you.) I used to say "snorkel" just to see what would happen, but I have tired of the disrespect. I'm a diver, yes, but I spend a lot of my time at the surface and/or interacting with the first few feet of water. It's warmer up there too, by the way. Maybe I'm just a swimmer . . . but I do like following the fish around down below.
Thought not quite plumbed here.
