Uncertainty

You say nothing lasts forever
You wait for the time to come
You say everything must change
But what if you're wrong

You say circumstances change
you can't expect to always feel the same
Is what you call reality 
a self-fulfilling prophecy
Is this some kind of lesson 
in built-in obsolescence
How can you be so certain 
about uncertainty

If I could have anything that I desired
I would change your mind
