I'm linear, but still i'm nice

We spent the first week of our May project designing the project plan, or in KP language: the "game plan". It's fun, its colourful, its associative and when done properly, its even strict.
Our supervisor looked rather puzzled when he saw it. "What did you call it?"
He quickly grabbed a pen and flipover and started to translate our gameplan into something he could understand. All the colourful lines and drawings changed into few words with some lines connecting them.
Next to me, Inga turned more and more red, until she burst out: "you're so linear!"

First thing in the morning of the following day he asked her what she had called him again. "Linear?" It turned to be the running joke of the month. He's linear, but still very nice...
