Train of conflicting thoughts.

Indian trains are crowded. People who travel in them belong to all age groups and all 'socio-economic classifications’. Unlike the train you see in this commercial. This one is an advertising paradise! All travelers are of SEC A+, or thereabouts and belong to the 25 to 35 age bracket.
No amount of deo can help you in Indian trains, and you don't get to move your arm to reach for the deo in your bag, let alone spray it on yourself! But here, there is room for all the good-looking and flirtatious co-travelers you can fit in thirty seconds.
Here people don't mind if you sit on their luggage. They don't mind your kiddish behavior when you play 'bike'. In fact, others join in and wave goodbye when you get off the train because you are such a cool guy! (Well, sitting on someone else's luggage is the only touch of realism, but it is not followed by people questioning your parentage, your sexual preference, etc).
Demanding suspension of disbelief from your audience is not wrong. But it should be for an effect worthwhile. Look at the way Axe demands it in the following commercial and you will see what I mean.

The Parx commercial demands a two-day fast. Partly because what it is, and partly because I still have bitter memories of my youth when I used a deodorant, and it did not work the way the ad said it will.
