The Traffic Signal.

Have you ever been on the signals on Indian road waiting for it to turn green? If yes, then you will understand this. In that small time period of around one minute, at least two-three poor kids, a lady with 6 month baby in hands or a youth with fashionable hair must have come to you selling something. They sell either the sun shades for car windows or painting books with alphabets for kids or umbrella or dust bin bags or peanuts or national flags or some small home decor thing etc. Don't you find this interesting that they have tapped this signal place as potential marketplace?

And to whom they are selling their products? To those who are going to fashionable malls for shopping by their cars with the car windows closed. So in this era of fashionable malls and online shopping, these poor street sellers have found out traffic signal as the potential market where everyone has to forcefully stop and these sellers get opportunity to at least exhibit their products to the people who otherwise would have simply neglected them. 

So when everyone inside the cars are willing for the green as soon as possible, those outside on the roads are praying for red for little more time. For the insiders signal might be frustration but for the outsiders it is hope!
