In Karachi, before a big rain, everything stops for a second. It wasn’t rain; it was a wall of water. It’s a strange feeling, being completely stuck, watching your loud, crazy, vibrant city get washed away into silence. The rain was a constant, drumming noise on the roof, and it kind of numbed you out. Army doctors, without a moment’s hesitation, had set up makeshift medical clinics on patches of dry ground, treating injuries and caring for the vulnerable.
