At the Karnataka Road Transport Corporation bus stand last week, I noticed this strange sight:

The pot was not there to provide a home for birds (in fact, I would say that pigeons and crows rate as pests and are not encouraged there) and it was upended in a net, so that the opening of the pot faced down. I could not find anyone who could give me a reason why it was suspended from the roof of the bus station. Any explanations, anyone?
