Waiting for spring to come is in many ways similar to watching a pot put on to boil. There's the long period of finger drumming, of looking and listening for sure signs that something's happening. But spring itself is more like the cat at the door; it'll come in when it's good and ready and not a minute sooner. You can stand there half your life holding the door open. Long waits can get pretty maddening though, and many's the cat who's had a door slammed in its face for taking too long.
