The psychology of it all is intriguing... case in point:
It matters not that there remain many inches of snow on our roof, several feet on the ground and icicles hanging from the gutters. Why? The days are longer, at both ends... Old Sol rises earlier and sets later. It was brilliantly sunny yesterday, with no wind. Temps only reached 38 degrees, but you would think it was a tropical day, here in upstate NY. In comparing notes with friends and relatives, it was not just I who turned off the heat and opened windows; rode with my car window down; dressed for Spring; soared in disposition; and, like the Energizer Bunny, flitted about to overachieve.
It's all relative... but hey, it's time.
