To approach the stranger is to invite the unexpected, release a new force, let the genie out of the bottle. It is to start a new train of events that is beyond your control.
T. S. EliotAnd the lost heart stiffens and rejoices in the lost lilac and the lost sea voices and the weak spirit quickens to rebel for the bent golden-rod and the lost sea smell quickens to recover.
T. S. Eliot[On The Waste Land:] Various critics have done me the honor to interpret the poem in terms of criticism of the contemporary world, have considered it, indeed, as an important bit of social criticism. To me it was only the relief of a personal and wholly insignificant grouse against life; it is just a piece of rhythmical grumbling.
