What thangs are he doin? Can't he be more specific? I tried to listen to the song dozens of times, and still can't find the answer. I suppose the song contains deep metaphor of what's going on in our lives, do we know what we are doing? Are we doing thangs? If everyone's been keeping us from doing our thangs, should we still do it?
Doin thangs, I suppose, is about finding the meaning of your life while you get high with bears.
