What else explains the mad rush for fellow passengers to alight? As the bus nears its stop, people from the back storm to the front. As the bus stops, others will get up and into the aisle. The line to get down is clogged. But they don't mind standing uncomfortably, rubbing more than shoulders with people in front and behind them. All they care is that they be out into the open, where presumably, they will be saved (yet again) from the poisonous gas slowly filling their empty seats.
Me? I sit down defiantly. Some kind of sit-in protest that is doomed because, well, I do also have to get down at some point. Sometimes, I swing my legs out into the aisle. It announces to the hyenas behind me that yes, I want to get down too, but can't you see that people seated ahead of us must be allowed to get down first? And where are your manners? And do you have to get down in a group? Clearly, the signal is too subtle and packed with too much information, because they rush past me, stumbling and saying "sorry" without meaning it. I must be acquiring a criminal education in sparking off stampedes.
It's funny, this urge to dismount at the earliest. There's no visible advantage in having to wait for 2 more seconds. People who are supposed to get down don't stand in the middle of the bus discussing the Kashmir issue or whether P is not equal to NP. So what are the rushers afraid of?
That leaves only one explanation. But it can wait - it's time to go.
