结点

You should let your mom know of that. Because your mom is the one who loves you the deepest, and at the same time, he has your deep love. The distances between your mom and you, you and him, one is so short and the other is that far. And you are the crosspoint who make the two unrelated life be involved in this same space.

请你一定要让妈妈知道，因为妈妈是最爱你的人，而你也深爱着他，一个很近一个很远，而你是将两个无关爱的生命体柔和于同一空间出现的凝结点。
