It is interesting to contemplate how easy it is to equate the elegance and romance of a moment to the person who was there with you during it. How many relationships have been started or pondered or desired because the beauty of that experience was so grand, so epic, that the only way you could conceive of another like it was if that person was also present, only to find out they had absolutely nothing to do with the pure Magic of that moment itself.
It is quite possible, I think, to fall in love with a moment, and because that moment is so fleeting, so ephemeral, you try to recreate it over and over with those present at the time, and maybe you succeed once or twice but it never really matches that initial beauty.
The only solution that I can see is to allow more beautiful moments to be Seen, and to fall in love with every single one of them. Your world, your very Life, would be full – Full! of Beauty, and Elegance, and Romance, and sometimes, if anyone else was with you, and they, and you, were paying enough Attention and Devotion to their own Experience you would each have another with whom to look back on those singular, amazing moments and sigh at the exquisite Beauty of them.
And that would be a bonus, but not a requirement.
