I love walking away from a film or book, when the credits roll, or the back cover is closed, and I feel the quiet. That quiet feeling that what you just took in was something that made you think, made you feel, made you be human and experience what those characters in that fictional (or perhaps non-fictional) felt in that moment. If done well, you understand what they are as people, who they are.
Well, I'm feeling in a very quiet mood as I just partook in an experience of lives, many lives, all living and dying, seen through the lens of one man. I just finished reading Daytripper from Vertigo comics, and the feeling I'm left with is causing me to sit down and write this at 5am. Its a feeling I don't want to be fleeting, and I'm scared that if I fall asleep I'll wake and the feeling will be less or perhaps gone.
And when hopefully we all walk into our proverbial ocean at the end of our days, we can look back and realize that we were fulfilled by what this life gave us.
Personally, I just hope I can look at that horizon with a smile, because even though I'll know that this life is over, I can see that something new yet awaits just beyond my sight.
Your experience may differ, but I'd recommend reading Daytripper to find out what that experience might be for you.
