whyever so ?

now went out during lunch hours to buy a bag. well, that's not the point here.
as usual walking by people, rather walking by smokers, got some of the stuff up my nose as well.
now i am not a smoker, but what i cannot understand is -

in india, a similar wiff used to really trouble my nostrils, and i didn't really like it. but ever since i came here, and anytime i became a victim to passive smoking, i have realised -
1. it doesn't trouble me much - neither as a smell, nor the affect
2. at times infact it is anti-repulsive (now i didn't want to use the other word)

and i have no idea of why so

1. is it coz' it's colder here (this i have been telling myself is reason no 1)
2. is the quality of cigs better, uhh, filter, and whatever (i wudn't have any idea about it)
3. is it that i have suddenly developed a liking to the smell (i do not think it's this, as i don't like the same smell when it's trapped in lifts, but then...)
4. none of the above - i have just forgotten the 'actual' smell of the same back home ?

well this is not important though, just a thought which i get each time here.....

off to a vacation after months.......so that's what's important right now.
i guess the wiffs and puffs can all be ignored !!
