Cover art for Circles lyrics by Soul Coughing

The last half of the song seems to be about the breakup.

"When the gas runs out, just wreck it, you insured the thing," is such an great lyric I think. It just describes the philosophy of a person who would rather walk out on a relationship (or anything) rather than fix a miniscule existing problem.

@Taobeth good interpretation
