Education of the masses in Berlin

We were on a train sitting across from a guy, wearing a black t-shirt and commo pants, who was playing with his pocket PC. Next to him sat a huge fellow who reaked of alcohol and who could barely keep his eyes open. The huge fellow was curious about the PPC so he asked.

For the next 10 minutes the first guy explained everything you can do with a PPC to the second guy in a friendly and understandable manner.
