How long?

I once had an adorable colleague during my journalism days who would remain unfazed by whatever happened around. She rarely responded with words under such circumstances. In fact, her only response to any kind of change in the system was “Kab tak?” delivered with a stoic face. In her long career, she had seen all kinds of restructuring. Nothing surprised her anymore. The editor is changing? No big deal. The team is realigning? No big deal. The page formats are changing? No big deal. To her, permanence didn't exist. She would keep reminding me that nothing would remain the way it is. Sooner or later, somebody new will walk in with newer ideas and somebody old will be going out pretending to be awesome. Today, more than four years after i heard that question for the first time, i'm yet to come across two more powerful words.
