Cover art for Spider In The Snow lyrics by Dismemberment Plan, The

I don't know that the protagonist in this song is specifically going out of his way to avoid ties, but that he is untied and lost and lonely and doesn't make the effort to make the ties because they just aren't coming to him. It's typical post-collegiate depression after being a part of something as rich and constantly active as collegiate life, being out on your own with no friends, working temp jobs to make a living will make anyone feel lost, alone, and confused. And I think your Spider in the Snow theory is dead on, PBCrunch.
