Memories often seen as useless by others become a sentimental afterthought. They build and act as the backbone for romantic relationships. Love adds worth to an individual's quirky mannerisms and creates a sense of fondness or appreciation for experiences that may have been considered unpleasant in the past.

This reminds me of a popular Chinese song, "The Moon Represents My Heart" by Teresa Teng. In Chinese context, the moon is an indicator or symbol of love. It is believed that when you look at the moon, your heart is yearning for someone.

From full moon, to half moon, to crescent moon, to several moonless nights, to crescent moon again, then half moon, and finally full moon... the moon constantly changes from phase to phase throughout time, similar to love. At times, the moon may "disappear" and feelings may seem fickle or fleeting, but they always return, replenished and constant.

Irregularity of feeling is not love. If left that ambiguous, that person, give or take, probably was not a defining figure within your life. Either you know or you do not. Harboring romantic feelings for another people outside of the relationship is impossible; there should be no room for petty crushes. If I love someone, I should only see that person and no one else.
