There is something to be said about the feeling of being back home. It's not something you can describe. The word 'home' alone invokes the kind of sentiment that we can all understand but can never really articulate. Its a feeling of comfort (that is about the closest explanation I can come up with). When I came back from Singapore and waiting in the immigration line, waiting for my baggage and asking someone to give way in Tamil and then hugging my mother, it was like something about me calmed down.
Just wanted to say that. Will post in more detail later.
