A glass half full

A glass half full
What would you espouse?
A glass half empty or one that’s half full,
Seems like a tough toll.
If you pick half empty,
You present like you still need plenty.
It would regard you a pessimist,
Who sees everything unprejudiced.
If you pick half full,
You seem faithful.
It would regard you an optimist,
Who sees no chance as missed.
Most can’t decide,
Upon favouring either side.
They are thought of as ideal
And are definitely not unreal!
