In this video, at first it seems as if Vi Hart is trying to work through some broken relationship with an existential exploration of self in a poem. Then she repeats the poem and it turns out that it is indeed about a confusing and sometimes upsetting relationship, but not the kind of relationship you probably imagined the first time through. This video requires a little bit of advanced math understanding, but wow! Outstanding Vi... simply outstanding.
Monika suggests that this might need to be made into a country song, while i think it should have been filmed in black and white... very Film Noir-style.
