To some special ones...aquarius always be prone to keeping distance, because in his heart it's not the best thing to become couples just for the human needs...so to the special one, he always hope that the relationship between them should be last forever, once they go beyond the friendship limit, maybe some day, their affection will fade....then...how pity it will be...for the sake, aquarius would rather look at him/her silently at a long distance than fall in love with him/her, only by which their relationship can last forever....

对于有些人，瓶子始终是舍不得，舍不得因为男女之情跟他在一起。因为这个人，瓶子觉得跟他的相处应该是一辈子的事情，如果真的成为男女朋友，也许哪一日，感情褪色而分手。那样，该多遗憾。于是，瓶子宁愿永远这样默默的看着他，地老天荒，却无声也无言。我觉得后边的解释。。。更像是说，喜欢保持距离。。。so。。。。
