Some people say they have a 'special song' that is iconic to their relationship/marriage or whatever
Or it might be a special book (more quirky I suppose).
I tried to find such a thing with my second ex and everything was rejected, so I stopped trying. One of our first dates in 2013 was to a Kasey Chambers performance at her brother Nash's rural property near Laguna (Australia not in the USA), but even those songs meant nothing to her as links to strengthen the bond I tried to build with her.
Do you have a special song/book/movie/etc. that is iconic to you with your current partner, or a former partner?
