Definition: expressive of or appealing to sentiment, esp. the tender emotions and feelings, as love, pity, or nostalgia
Can sentiment be escaped? I do my best to not get cheery eyed when true love beats the odds and conquers all. I don't know true love, and I do not know if it exists. I know joy, sadness, pain, pleasure, and a few others. I feel joy when I gambol through the woods or watch my niece play. I feel sadness when I don't get a job I want or when a tragedy takes a life sooner than I expect. I feel pain when a Bald Eagle pinches my skin through a glove or I touch a hot pan. I feel pleasure when I drink a well-crafted beer or a friend massages my shoulders. These emotions are easy to describe in simple scenarios.
True love is not so easy to describe. What defines true love. Many epitaphs and stories attempt to answer this question. Theories like: there is only one soul mate for each of us and we will know them when we find them. I am more enthralled by the lust of Pan's flute than this illogical search. I have heard the lyrics of love songs. They have been flooding into my head since my first Hank Williams record. The Beatles wrote, "All you need is love, dadadada." I want love, but I don't need the cookie-cutter kind. Love is all around me. I can love without true love.
So why this concept of true love?
Sparrows soon. One of the White-breasted Nuthaches bore a small grey bird band. I suspect it was one that was banded here at Audubon, but I did not have the time to read the numbers. 
It was a cold January morning in Petersburg, Pennsylvania, abnd I was receivinga crash course in common winter birdfeeder birds. Although it was not until 3 months later that I became enthralled with ornithology and the joys of bird-watching, I will never forget the excitement of watching a white-breasted nuthatch flying back and forth between a feeder and a tree on that bugar-freezing day. At the time, I pondered why the nuthatch ate that way when other birds chose to eat their seeds right at the feeder. Why did the nuthatch use up all that energy going back and forth? Since then I have become a birder, I find the august song of a winter wren or a sneak-in visit by a hermit thrush to be tantamount to or exceed any experience I have had at a zoo or circus. In agreement with me would likely be Marie Winn.
