Perception

So we went sailing, and I forget my sunglasses, so Manus buys me a pair on the dock. My new sunglasses are the exact same as Manu's Vuarnets, except mine are made in Korea not Switzerland and cost two dollars.
Three miles out, I'm walking into deck things. I'm falling down. Manus throws me a rope, and I miss it. Manus throws me a beer ad I miss the beer. A headache, I get the kind of headache God would smote you with in the Old Testament. What I don't know is that one of my sunglass lenses is darker than the other, almost opaque. I'm blind in one eye because of this lens, and I have no depth perception.
Back then I don't know this, that my perception is so fucked up. It's the sun, I tell myself, so I just keep wearing the sunglasses and stumbling around blind and in pain.
