It's interesting to see how people make use of the time they spend on public transport in Indian cities like Delhi and Mumbai. In crowded buses and trains people manage to take a short nap and some even reach the snoring stage. Or they spread out a newspaper over multiple knees and arms to read about the latest sport results or political crisis. Then there are the experienced travellers who have been playing cards with the same group over the last decade or so.

Travelling by public transport is being in the thick of the seasons of life -- a sweaty life in summer where people, blissfully unaware of the rivers of sweat running down their brows and inside their clothes.

It is impossible not to see every little flower by the wayside blooming proudly. And the warm sun manages to transmit some of their pleasantness to the inside of a bus or train. Now, wouldn't it be perfect if we had a public transport worth the name in all our cities? If you see people in colourful clothing and breathing heavily, you are probably travelling during the   _  .
