求翻译：（1） 当一对单身男女相处久了经过了一些事情，潜移默化中会对彼此产生一些感觉。但这些感觉又不能使双方马上确定为男女朋友关系，总有那么一瞬间有一个人决定就是他/她了。那么这个决定性的瞬间就是他们在相处这段时间以来的转折点。是什么意思？

(1) when a pair of single men and women get along long after a number of things, may cause some to each other in subtle feeling. But these feelings can not bring the parties immediately established for male and female friends, there is always a moment a man decides he/she is. So they get along in this decisive moment was turning point since this time.
