Onset of summer - indirect reasoning

Thanks to my extraordinary skills of observation and deduction, I have now reasoned that summer has started setting in Chennai.

I even ignored the fact that I have started sweating a lot. Threw away the fact that I've started feeling the need to drink water a little more. I totally avoided considering the fact that I am having ice-cream daily for the past 2 weeks.

But, last week, while travelling by my company bus in the morning, I noticed a few girls wrapping their respective dhupattas over their respective heads. That got me thinking. Why would girls in this day and age want to cover their heads? These were all not North Indians and even if so, they were surely not in a temple (even if you stretch your imagination of 'work is worship', this bus is not a temple).

So why? Then I realised that they were protecting their hair. From what you may ask? The answer is the air outside. Air that is so polluted and dusty. This would affect the hair's health.

But then its air outside the bus. Why should those inside be worried about it? That's what I thought. Then I let the matter inside my cranium do its job and reasoned that probably the outside air was somehow entering the bus in great volume and this must be why the girls were afraid of damage to hair.

But how will the outside air enter the bus with so much volume? Simple answer. The windows were open. A-haa! Open window in a fast moving vehicle, like our office bus, is potentially prone to let large quantity of outside air into the vehicle.

But wouldn't the windows have been open always? You have a pertinent question. But, since there was winter (sic) in Chennai from Dec to Feb, the windows were usually closed.

But if the windows are open now, it can only mean that people have started realising that Chennai is not that cold now. Since we don't use an A/C bus, naturally some of the occupants want to have open windows. Which then means that dirty air comes into the bus. Which implies damage to air and so the girls cover their heads.

All in all, this only means that summer is here.
