Half full or half empty?

Yesterday, Lucas and I were reading volume 6 of the chronicles of Narnia which we're both enjoying. We came across Puddleglum. Definitely a half empty marsh wiggle. We spoke a lot about how much better it was to be half full and that you just had to make the decision to be positive. A useful lesson for me! Walking in a brief dry spell I saw the duck. She looks happy enough.
