Lyric discussion by timbo 

Cover art for Pale Green Things lyrics by Mountain Goats, The

I thought that the "pale green things" was a way of equating scraggy grass growing in hostile conditions to him growing in similar difficulties. They may be pale green things, but they are tenacious, alive, and can derive some pride or satisfaction from the struggle.

I have to add to Timbo, I think pale green things are plants which are barely alive. With just enough chlorophyll to sustain them. A metaphor for his stepdad, or maybe his life up till that point. You may not have everything you hope for but you have something. And from his perspective it's everything. And if you think of it, the experience is rich and bears its own fruits.
