I think that we all regret wasting precious time on people, although, in the end, you can never know what time was or was not "wasted." That's likely not our place to judge. Perhaps, as many of us believe, God turns all human encounters toward some purpose of His own, and the best thing that we can do, as we stumble through each day trying to make sense of our lives, is to trust in His ultimate mercy and justice.
That said, I prefer sharing a piece of literature or music, a poem, or another work of art that I think is beautiful with another person who also finds it beautiful. I do not want to waste their time by sharing works in which they are so uninterested that they can not work up the energy to even respond, or, perhaps worse, by making them feel obligated, as a matter of common courtesy, to make an insincere compliment. Therefore, I think it might be more appropriate to throw these items into cyberspace, via this blog, where manners do not require a response, and where anyone stumbling across this obscure rabbit hole in the universe can move silently along if something he or she reads, hears, or sees here does not strike a chord.
Morten Lauridsen set the poetry of Rainer Maria Rilke to music. To me, the beauty is transcendent. Perhaps to one or more of you, it will be the same.
Abandon entouré d'abandon,
tendresse touchant aux tendresses…
C'est ton intérieur qui sans cesse
se caresse, dirait-on;
se caresse en soi-même,
par son propre reflet éclairé.
Ainsi tu inventes le thème
du Narcisse exaucé.
Wildness surrounding wildness,
Tenderness touching tenderness,
It is your own core that you ceaselessly caress,
... as they say.
It is your own center that you caress,
Your own reflection gives you light.
And in this way, you show us how Narcissus is redeemed
