Guys. This song is about how nothing in this world lasts.
Not people, but obviously they've always died. Not fun. Not things we buy or marriages. But the problem is that we have to pretend like, "oh that's normal, that they divorced, or it's natural that i should spend 8-10 hours a day sitting in my office without any feeling of what I've achieved."
Life changes so fast, nothing in it lasts, and the song is of the anger that everything's temporary, we can't hold on to any feeling (even from drugs), and we're supposed to pretend that's normal and should be that way.
