You are travelling to the train station (going home after work) in a tram, and you spy a friend. Do you:
1. Jump off (after the tram has come to a complete stop) and say "Hi".
2. Send a text message saying "I can see you".
3. Ignore the person completely (leaving the possibility that you might be seen and henceforth known as a snob).
4. Post a message on Blogger.
5. A combination of the above.
6. Something else.
Your confused Melbournian,
