Oh, the sword...

Oh, the sword is a representation of how as an adult you have to keep all the business of your life up, like spinning plates or balancing a sword on your head. And that's why you have such a hard time reconnecting with friends who you've fallen out of contact with!

It represents all the burdens and responsibilities of your life, under which you have to learn to dance with grace and smoothness.

Cool! This will not have any effect at all on what the dance looks like, but I do like to keep my story coherent ;)
