How can anyone be sure that they are in the now? People have this weird idea that things around them are happening now. But what is now? It all depends on perspective. I should know because my 'now' is constantly changing. Hear is a poem from the future (your future) that explains it all...
Where are you in relation to time?
Then, now, or I'm still waiting?
Are you experiencing this or
Is it just a memory?
See you, I'm off again. Hope you enjoyed the future poem - there are lots of good poems in your future! Enjoy.
