Thankful

No idea. Anyone?

'Forgive me my tongue It doesn't know what it's doing It used to get washed out Now it's undisciplined and crude I'm losing my language And calling a truce And the shape of the thoughts in my head Aren't right for the words I've got to use'

i think its about someone who hasnt dated in a long time because of a 'bad' breakup/relationship. they dont know how to act or what to say around new people or maybe their past relationship was controlling and now they dont know how to act without the other.

'Hey, hello, how do you get on With so much undone, and still you shine like a sun'

I think this part is about seeing an ex and they act like nothing relationship-wise happened between them. according to him they have some unresolved issues from the past

I'm pretty sure the previous comment is completely wrong about the meaning.

I would agree Mitchious05 is off on the meaning. I don't hear that at all.

What I hear has more to do with the state of the world and us as temporary creatures here. This particular section gives the most evidence to my interpretation:

White dwarf, red giant It's empty in space And where there's matter there's violence I never got it, I never got it before

The protagonist is constantly coming to terms with what it all means, existentialism, and speaks out against his (and all of our) eventual fate in dying. His language ultimately fails him in this case because who can possibly explain the complexities of life, death, and why we're even here?

Although having said all of that he comes to the not so bitter conclusion that "we have a lot to be thankful for". It's a bit tongue in cheek maybe, but also very true if you consider his ability to live before dying.
