Falling in love with a stranger.
No, you’re in love with the idea of loving this stranger. There is a huge part of you that knows you two will never be, but then there is the other part of you that has this faint strand of hope that you two could be— if the circumstances were right. But the circumstances are almost never right, and things never go your way. So you both drift away. Nonetheless, that faint strand of hope will always stay.
