If only
Someone senses
Unsaid
Unseen
Either he(she) is a mad
Or a poet(Poetess)
Or could be the both

A test
Is enough
Pour some liquid in a glass
Ask, what do you see?

I don’t know what
Mad replies

Poet(Poetess) never makes
Let you down
When he(she) is full,
He(She) sees half empty
When he(she) is thirsty,
He(She) sees half filled

Only if
You are sensible enough
You will know

When to add
More liquid
