Not strictly speaking a threshold perhaps, but definitely “a point of entering”. This photo was taken on my first trip to India in 2005 (which seems a long time ago now). I sometimes think back on this trip as a time of innocence in a way because at the time, we were as yet unaware (but would soon find out) that cancer had started its quiet but devastating work in my father’s lungs. Another threshold so to speak. There were to be no more trips to foreign countries for a long time, and I would not return to India until 2010.
