One line means that your life will not change. That everything will continue to exist as it was before. That you'll be the same person that you were ten minutes ago. That everything is, and will continue to be, yours.
Two lines means absolute change. Means giving yourself completely up as a person. Means that you'll be new, different. Two lines means that nothing exists as it was before. That nothing belongs to just you anymore. That your life will be shared.

It was the only test I ever passed that I kind of wanted to fail.
