Taste is the most selfish of all the senses. When I see something, I don't diminish the object by viewing it. When I smell something, I don't take the aroma away with me. When I touch something, I usually leave a bit of myself behind. My hearing something doesn't trap the sound waves or in any way inhibit your ability to hear it.
But taste: you can't taste what I taste. It's gone, forever adulterated by enzymes and teeth, and even if you could, somehow, eat the very same John Wayne Omelette, just as we could see the very same sunset, smell the very same jasmine, caress the very same skin, listen to the exact same Sonics album, you might not like it as well as I did.
And even if we do share the same experiences, there's no accounting as to how we actually experience them. Just because we both recognize red doesn't mean my red is your red.
It's a lonely life sometimes, but it is my lonely life.
