I think this is missing the important point that the glass isn't full of milk. That's horse semen

Nonsense.
The glass is always full. Liquid in the lower part, air in the remaining top part. Ask any engineer.

People seem to forget that the glass can be refilled.

I always see just a glass of water, and then I ask may I drink it?

I then get told I'm not taking my sessions seriously....

It's always full regardless the amount of fluid seen.
Nothing doesn't exist.?

It's not about whether it's half full or half empty, rather how the person who sees it views it. To say that "the glass is half full would be a negative", is the whole point, to determine how a particular person approaches life.

My glass is broken.

how should i know im blind

It is all subjective. It depends on your point of view. Both opposites are true at the same time.

you glass is always full or it would be a vacuum

But there is a difference,
the half empty glass has a fly in it.

Neither....the glass is twice as big as it needs to be.

It depends on what's in the glass.

The pessimist says the glass is half empty
The optimist says the glass is half full
The engineer says the glass is twice as big as it needs to be
The physicist says, the glass isn’t there
The Nihilist says, you can easily get a smaller glass
I say—"It’s a double… bottom’s up!”

To me it's always been; the glass is half empty if you're draining it or; half full if you're adding to it.

If you're discussing liquid in a container, you're not discussing the philosophy behind the question. You are criticizing philosophy without understanding it.

I've always thought this glass half full analogy to be ridiculous. Thanks for calling it out.

It could be half empty or half full, but it’s more likely that’s its 6/7 empty.?

People who se the glass as half full lack foresight and the willingness to accept inevitable consequences.

It isn't meant to make much sense in literal terms. It's a metaphor for optimism and pessimism. Trying to see the positive or insisting on focusing on the negative. It's valuing what you have left rather than lamenting over what you've lost. A 'glass half full' person gets half way through a holiday and still enjoys the rest if it. A 'glass half empty' person spends the remaining days brooding about going back to work.

Technically it is a trick question. The question is a matter of physics. The glass is full at all times with the particles that make up water and the particles that make up air. The question is thought to be one of the psychological interpretation to show ones pessimism or optimism.

"Behold! My child has consumed half her fucking milk! She hath conserved the other fucking half. Ergo the glass is BOTH half full and half empty" I don't have kids, so drink that shit bitch. That shit costs money!

An optimist says the glass is half-full. A pessimist says the glass is half-empty. An engineer says the glass is twice a big as it needs to be.

Seems you already have the answer so no discussion necessary !
