Public Transport Etiquette
Rule 4: When speaking make sure your voice is at its lowest possible level

There are two main groups that this rule applies to. Firstly, are school children, particularly teenage girls. Having been trapped inside all day, being artificially suppressed and made to be quiet in the classroom there is an explosion of excitability on being released. This largely manifests itself in much shouting, raucaus laughter, singing, bullying, slagging each other off. Unpleasant as this may be on the street its impact is magnified tenfold when taken into the confines of a bus. It is not big and is not clever - actually you get shown up for what you are (and this is in direct opposition to what you hope to be perceived as).

The other group that this applies to are the mobile phone users. I would never want to bring in such draconian measures as they have on some trains with a banning of use of mobiles in certain parts of the bus or at certain times, however, I have never understood why so many people seem to have to raise the level of their voice while speaking on a mobile so that everyone on their deck can hear every word. The rest of the world neither cares what you have to say nor wants to listen to half a conversation you are having. Give us a break and speak quietly.
