Sir: As we deal with the aftermath of the dreadful Peshawar attack, our hearts mourn. And as we mourn as a nation, people join us from across the border signifying that we not only mourn as a nation but rather that we mourn together as human beings. People from all over the world have shown solidarity, whether by lowering the national flag to flutter at half-mast or by lighting up vigils or even with hashtags like #IndiawithPakistan. Every gesture of sympathy, every candle lit, serves as hope for humanity. It reminds us that humanity knows no borders, blood that flows in us is the same, the heart that beats is the same and so too the tears we shed are the same. While the circumstances under which we have united are sullen, it is still comforting to see how the human in us has not died under our nationalities. Right now it is evident that the world has its fair share of good human souls and that all is not lost. Not yet. The light of hope still flickers, despite the darkness. ABEER ANWAAR Karachi
