Falling off a bike as you're learning to ride it (because the person who was helping you decided to let go), getting all bloody in the process, and getting up (after you've had a good cry) are like bits of life in general. (If you're all confused about the point I'm making, read the post below, haha!)
You learn something--sometimes with the help of another person--then you're left alone; you screw up; you recover and do a good job even with that other person in absentia.
The shoe can fit the other foot, of course. Sometimes you're the one who decides to let go, cut the other person some slack, let him or her discover the joy of flying alone, of living, without you having to worry about every possible bruise and scrape; knowing and having every confidence that he or she will be fine, notwithstanding the bloody knees and elbows. You do it because you love them with every beat of your heart; you are ecstatic for them in their pursuit of their joy, their passion, their enjoyment--whether it's dancing to acid jazz or riding a bike.
You sometimes find yourself hoping that the people who matter to you think the same way about you. That they're in full support of your most personal and deepest quest...even if it means that they--or you--recede from the line of sight. That your (or their) eyes drinking in the sight of them (or you) waving bye-bye or fare-thee-well is shocking, however expected it may be. But then, the heart and soul see much farther and further than the eyes ever could, don't they? So the line of sight is never fully severed.
Because no matter how near or far they are, no matter how much you miss them (or you yourself are missed), no matter the words exchanged (or lack thereof), no matter how much you love them (or are in turn loved), the underlying mutual feelings and support hold fast and true. I think this is true also, even though you find yourself falling into a frenzy of (sincere!) well-wishes for that other person's happiness--even as you miss them terribly and feel miserable at stepping aside in order for them achieve their dream.
N.B. The Cure is one of my favorite bands and I simply adore Lovesong. Thanks to my blog friends Natalia, Houseband00, and Deb, who inspired me to remember just how wonderful Robert Smith and company's songs are.
