You wish you could sit and do nothing all day. You wish you had an excuse to stop time, just being tired isn't enough to stop the world, others have it worse than you and they go on stronger than you. It's 2 and evening is creeping closer.
You've already wasted part of the day away, why not sit a little longer? Who's to stop you from staring off into space and never getting anything done? Nobody can truly make you do anything. The world goes on without your contribution to society.
The Sun is gone past the mountains. How could you become so tired after only thinking? You forgot to eat, that's it. Even that can wait. You'll go to bed and do something productive tomorrow. On the other side of the world life goes on without you.
