Pick up the pen, now put it down.
Only to pick it back up again.
I used to be so creative and free,
so whats this strange thing that's happening to me?
Is this some kind of disease?
Will you catch it if I sneeze?
Or perhaps it's only mental
and I'll capture something when it's truly sentimental.
So now I'll leave these paper sheets be
and continue walking to see what I need to see.
