But I also think all of the great stories in literature deal with loneliness. Sometimes it's by way of heartbreak, sometimes it's by way of injustice, sometimes it's by way of fate. There's an infinite number of ways to examine it.
If you've got to my age, you've probably had your heart broken many times. So it's not that difficult to unpack a bit of grief from some little corner of your heart and cry over it.
