Lyric discussion by Sporkah 

Cover art for Long Division lyrics by Death Cab for Cutie

Is it just me, or does anyone else think that the 'open door' referred to, is also a metaphor for the open door of a classroom- the student gets distracted by what's going on outside, and stops paying attention to the sums he should be trying to solve? Just something that popped into my head during maths class today.. dammit, i'm distracted by DCFC! ^^
