A couple of persons live in this body of mine, but there are two that prevail. One is outgoing, extroverted, overly excited and eager to socialize, drink beer and dance. The other one likes to observe, enjoys silence and peace, likes being alone pondering over life with a cat on the lap and a book in the hand. Nevertheless, I know that there is something in me and in each one of us, which goes far beyond the concept of personality.
