Half Empty Half Full And Half Truth

This is the 100th post.
I am going to publish my thoughts on the question: Is the glass half empty or half full?
 

It is either half, empty or full.
When it is half, it means the result of dividing or cutting a whole into two equal parts.
Empty is nothing, zero. Cannot be divided or cut, the result will still be empty or zero. Half empty is not real, only in words or language. No person can divide or cut empty.
Half full is also not real. Full is whole, complete, filled to capacity. It can be divided or cut but it will not be full any more. Just half if divided into two equal parts. Not full anymore, just half.
A glass of water divided into two equal parts contains half glass of water. Not half empty, not half full. Just half glass of water.

Mathematically, if the glass measures 6 inches in height then half glass is 3 inches of water.
Full is 6 inches of water, half is 3 inches of water and empty is 0 (zero) water.
Half full = 6/2 = 3
Half empty = 0/2 = 0

The question: "Is the glass half empty or half full?" is asking for half truth.
Maybe the right words are: half of the glass is empty and the other half of the glass is full.
If this is the meaning then choosing either half is not a complete answer.
The truth is we see both. We can see the whole glass even if our one eye is closed.

To say half empty is incomplete. To say half full is also incomplete. They are half truths. We see both halves and that is the truth.

Some might say that the empty part is not really empty. It contains air. Real empty is vacuumed. This is also true.

English - Tagalog

If you know Tagalog language, it will translate to: "kalahati wala kalahati puno". It becomes a joke. Because we just say "kalahating baso ng tubig" (half glass of water).
I remember "I have nothing". In Tagalog it translates to: "Ako meron wala" or "Meron akong wala". Also a joke.
