Human entertainment

When I was about seven, I asked my sister to draw a picture of me because I was afraid of her reality being different from mine. "I can see this red color, for instance," I thought, "but what if she sees it fluorescent green and names it red, like me, while seeing something different."
So, in a desperate attempt to feel less anxious, I asked my sister to draw me. I was terrified with what I saw on the paper when she was finished with her picture—a pretty accurate drawing of me with my Mickey Mouse sweater and my main physical features included. I was terrified because I came to this unsolvable conclusion: no matter how accurate her drawing was, and no matter how well she performed on any match-my-color test, I would never know how her actual perception of the world was (at best, I could only imagine it, as scientists do when they tell us how many colors a cat can see or, even further, how cats sense the world).
Soon after my sister's drawing, I heard that someone had once said "I think, therefore I exist." I started living a more entertaining life, as I would no longer need to worry about how my sister or my cat saw the world, I would only need to think my own world, and they would be automatically included.
The way I see the world has been changing a lot since that interesting event, but I still think sometimes that all I can do, based on what I feel, think and sense from the world (inner and outer), is wonder. As with many problems that I've had in my life, I chose to solve the phenomenological one with entertainment—sports, video-games and words. That's why I think that almost any problem has an entertaining solution.
Entertainment—to hold among something—holds us between the beginning and the end. I talk about entertainment that can be found not only in cheap magazines and gossip shows. Entertainment in art, in science or in technology. Touching entertainment in sports. Ever-ending entertainment in creativity. Written entertainment in books. Filmed entertainment in movies. Suspensive entertainment in questions; true entertainment in truth (if there's any) and false entertainment in fiction (if there's none). Full, transient entertainment in life.
As it might happen with my sister (or with my cat), it doesn't matter if we actually see, think, feel or sense something different when we use the word "entertainment" (or a less—for us—sophisticated meow), all that matters is to use it under the same personal conditions.
Although it may not last, I've come to an entertaining conclusion—entertainment supports almost everything we, as humans, do.
