"At first it was difficult and a little overwhelming but after a few days you'll get used to it." - 
Some first world cities have their share of slums, but they are often isolated that you'll not notice it. In Delhi, every class from poor to rich live in such close proximity that the contrasts were glaring.
Every street was littered with garbage...
...animals roam freely
...and of course, Indian traffic.
What's funny is a lot of vehicles have a "HORN PLEASE" sign since honking in India is a necessary act of caution to let other drivers know that "you are there".
Aside from non stop honk from the cars, spending hours to travel for just a few kms is not cool especially when you have a limited time.
If you are an avid traveler and looking for a different experience, I'd suggest go to Delhi at least once!
If you have a passion for traveling please don't forget to follow!
