From my personal experience, I think the so-called first love is the first love, because we don't know love, we are ignorant, we have done many wrong things, and maybe we have hurt each other deeply. This kind of love is often accompanied by pain; The second way is to talk about mature love. At that time, we gradually understood that love is a matter of two people, and began to consider each other's feelings, care about each other, devote ourselves to giving and enjoy the love from each other. This time is the sweetest; Third, people who have gone through vicissitudes of life are exhausted, because of various reasons, they have lost their second beauty, no longer have the confidence and energy to pursue that sweet burden, or have lost their freshness, become accustomed to sweetness, are tired of sweetness, and just want to be as light as the breeze.
