What's specific measure can prove it is a separation?
Is it the length of the river in Nile?
A hundred kilometer? A thousand mile?
Or is it the distance traveled by space station?
The answer is none of the mentioned above
Because separation only takes "one"
One heart slowly losing its love
One glance at another man or woman
One lie cloaking disloyalty
One foot walking away from commitment
One ear that cannot listen patiently
One word harsh because of an irrational disappointment
One thought of commiting infidelity
It all takes one, just one
To realize that person is not your sun.
