From Uneven Bars, regarding the lovers as twin flames:
"I feel I've known you a long, long time," he said, "And you knew I'd be waiting." (Actually, I said I felt comfortable, like I already knew you, and I hoped you'd wait for me. But I like the way you wrote it. Maybe we're both right.)
There are many sites on the internet describing love at first sight and soulmates who are twin flames. The lovers in Uneven Bars are twin flames.
