I am in a café, and this is my life in a nutshell: every time someone sits down I feel anxious, and every time someone gets up, I feel lonely. Why did they come here, for their coming here makes this place less valid, and therefore I become less valid, too? Then: why did they leave, what was wrong? What is it - the place to go - that they know and I don't? What is secret, what has not been revealed? Why am I left, unless something is wrong? Why do I know, deep down, that no one cares if I stay or go?
