Do you ever find yourself just sitting on the couch, staring out the window? Like in ten spare minutes between doing one thing and another? Even though it's not in your nature to just stare into space?
If so, have you ever been snapped out of staring-land when a tall, leafless tree on the horizon suddenly and quickly falls over? And then you sit there for ten more minutes, remembering what it sounded like and wondering if you have lost your mind and imagined it all?
I will do some sleuthing tomorrow, but Greg saw "tree trucks" (driven by trees?) on our street, so maybe I'm not tripping after all.
