h a l f glass

If you were to say to me is your glass half full or half empty.
I would reply with this.
A glass half empty has already filled,
Because you cannot fill a glass empty.
So we have to assume that half of the substance,
In the glass has been taken out.
A glass half empty means you had lots and it has been taken from you,
A glass half full implies there are limitations to ones fullness.
Of both I am neither,
My reply will be,

I drink from the bottle.
