I used to dig in the garden, and there isn't anything fantastic or ultradimensional about crab grass... unless you are a SF writer, in which case, pretty soon you're viewing crabgrass with suspicion. What are its real motives? And who sent it in the first place? The question I always found myself asking was, 'What is it, really?'
When I was a kid, I really wanted a metal detector for Christmas, convinced I was going to find buried treasure and could retire at 12. Santa Claus brought me one, but sadly, that treasure was never realized. It's amazing how many bottle caps you have to dig up. But to be honest, that dream is still alive.
