I'm on my way home from a lovely hike in a real forest--far from Groddle, but not without similarities. While saying hello to a passing hiker (because almost all hikers say hello), I thought "Huh. Hikers are (pretty much) universally friendly. Reminds me of Glitch. I wonder what the intersection of Glitches x Hikers is?"
"Hikers" being loosely defined, here. If you like to walk in the woods, you count.
