Sometimes it is incredibly difficult to capture and contain a description. One day as a child there was a peculiar and beautiful cloud formation over my parents' farm. I stayed and watched it in rapture until it was gone and then immediately rushed in to try and describe it in my journal. I wrote for pages but never quite managed to capture that feeling. The local paper simply published a full color photo but even that was a pale imitation.
On the other hand some experiences are easy to describe and relate perfectly. For instance I had to use a different rig at work today due to circumstances and experienced an entirely new sensation in the cab. I also relayed that sensation to my co-workers with a single sentence such that they immediately understood it in its fullness.
"Why does the Chevy smell like a pack of JuicyFruit puked up in the cab?"
