Love!
Seems awkward, right?
Lemme explain,
A major portion of the Eastern literature is about the lost love, the pain of not being able to meet and unite, and the joy that's being extracted from waiting for the letters of your loved ones, and, the list goes on and on.
Instead of the easiest way of dating and finding your match (or mismatch), I would love to fall in love with someone who's not as easily available to me as lovers are available to each other these days. I want to write poetry for someone and that someone writes me letters telling me how much they miss me and how lovely it would be, when one day, we get to meet, travel, or go out secretly on a picnic or something.
