I was more than 7,000 kilometres away when I first felt a strange pang in my chest that can only be defined as homesickness. In Barcelona, the chilly water of the Mediterranean Sea was licking my bare feet, and I was overcome with a longing for what I had left behind. I was to return to Mumbai soon, but at the time, five months was the longest I had ever been away. On the beach with me that day was the man I would later marry. This is what my city looks like, I said to him. This is how it smells.
