Proof that knitters view the world in a different way comes from Erika:

Outside our building is a sorry little sidewalk tree. At the height of summer, it had about five leaves. A dead glowstick has been dangling from its branches for three months. Tonight while I was out on a smoke break, I looked at the tree and thought, Man, that is one sad tree. It looks cold and wet and pathetic. It needs a sweater!! I went home and whipped one up, it only took an hour and a half to knit. Then another fifteen minutes or so, standing outside in the cold at half past midnight, stitching it up.

Erika even wrote up the pattern for anyone who'd like to follow her example.
