FALL

Sometimes we cross the same staircase everyday. We know every inch of these staircase, so well that we believe that we can walk down those stairs in the darkness of the night. And then one day in the bright morning you fall down those very stairs and you can't believe it. But you console yourself saying that once in a while this happens, its alright to fall once in a while from a familiar place, but this won't happen again. And then the next day when we walk down the same staircase we think about the fall and smile at the incident and then before we know it, we have fallen again, from the same familiar staircase.
And one never gets the reason for the same consecutive fall from the same place.
