Excerpt from one of Karsten’s messages:

“…and I entered my office and thought “Ok, I need a pen and paper!”. Finding paper wasn’t a problem, there is paper everywhere on the desk. Finding a pen went like this: opening drawer 1: no pen. Opening drawer 2: no pen. Pushing aside the paper on the desk: no pen. And then I pondered and I thought “Ok, I lately saw a pen in the lower left corner of my desk!” (I just got 8 new pens from office supplies recently). And there I indeed found a pen – although it wasn’t the one I was looking for but a different one”

Ps: I always feel the deepest sympathy with his office colleague who works on the desk at the right-hand side. The one where everything is put in a symmetrical way.
