Usually we get used to each other and take the things others do for us as granted as we get so close: therefore, we have aesthetic fatigue and finally become more and more indifferent .
In many cases, we become blind which results from closeness ; we get aesthetic fatigue since our heart is covered by dust ; in the end, the passion towards each other is fading away right due to the aesthetic fatigue.
we maybe often ignores because of the zero distance ; Because ignores, we can esthetic weary; At last,we become more and more desolate because esthetic weary.
In many cases, both physical and mental closeness result in our indifference; and the indifference brings about aesthetic fatigue; in the end, the passion towards each other will fade away right due to the aesthetic fatigue. 个人愚见
