half full or empty?

Hypothetically speaking, if you had a glass of milk or some other beverage and you drank half of it would you consider it half full or half empty?
I would consider it half empty because it was full to begin with so if you drank half then you made it half empty. Although, if you were looking at more optimistically you would probably say that it is half full because it started out empty and you filled it half up. Then you just pretend that you never drank that that other half.

Wow, that's hard to decide. I kinda think that you could say either way.

I think it would be half full. In my opinion, a glass is full untill it is empty. Its kind of confusing lol

It sounds that saying it both ways are alright.

if some give it to me as half, I would consider it half full, if I drank half of it, then I'd consider half empty
