The world in which we live is so confusing. I don´t understand anything but it doesn't no matter. I´m not a children but I would wish to go back to playing with my toys for an entire afternoon...without worries, no problems and laugh, running around the garden to save the world of from the evil. When we are were children the world was fantastic, wonderful, our eyes shone...I was happy. Now I´m a man who can´t understand the world. I´m not special, many people feel the same way. I´m getting older, my mother wants to grandchildren but I wan´t, first, I wish to learn to love the world again. All that is in our mind, the land where we lives  is the never the same.  I´m a bit shy maybe, my mind is not the same when I was a children.

I hope this was of great help to you. It was my pleasure. 

Thank you guys
