Final answer:
The statement suggests that a special and right person will eventually come into one's life, making past unsuccessful relationships make sense.
Step-by-step explanation:
The statement "Someday, someone will walk into your life and make you realize why it never worked out with anyone else" suggests that future relationships have the potential to be special and uniquely fulfilling. It carries an optimistic view that despite past failures in relationships, there is a person who will be just right for you, and with whom everything will fall into place. This notion aligns with the idea of not losing hope and being open to new experiences, because they can lead to unexpected happiness, much like the sentiment expressed in the poetic lines, 'If no love presumes a thing, You may wish to keep arms wide, And see what each day brings'.
