Optimistic

I weave through a sea of pessimists 
A lone optimist 
Their vacant stares and empty minds hold nothing of value to me
But, as optimistic as I am
I am doubtful 
Doubtful of the place I live
Doubtful of the people I know
Doubtful of the dull qualities the possess

I see the glass as half full
But what if the glass is knocked over
The liquid spilling onto a table, dripping down the side and pooling on the floor
What if the class is empty?
Again, the doubtfullness envelopes me as I no longer see the glass as half full or half empty

But as knocked over
Holding nothing of value
