In scenarios where the metaphorical glass is either half-full or half-empty, so
Thank you Andrew, for this thoughtful response. I have been wanting to respond with notions of false dichotomies and the like, but yours is far more probing and engaging. In my thought world, however, when someone asks me if the glass is half-empty or half-full (as my academic dean did once!) I simply say it is neither - it is time for a refill!
In Vino Veritas, and cheers,
