Sleep is something one must learn to overcome. I learned how to do it when I was a child. I never slept. And I had friends who even slept less than I did. The one who went to bed first paid a penalty. And we really didn't do anything. After seeing a movie we'd go to a cafe and discuss things for a while... then we'd sit down on a bench somewhere... listen to some drunkard... watch them putting up posters or manifestoes...or look at the sheep passing by... or go for a stroll around the market place... Or else we'd go and wake up some girl in the neighborhood by standing in front of her window and calling out her name...
