这种狂暴的快乐将会产生狂暴的结局，正像火和火药的亲吻，就在最得意的一刹那烟消云散。最甜的蜜糖可以使味觉麻木；不太热烈的爱情才会维持久远；太快和太慢，结果都不会圆满。
These violent delights have violent ends
And in their triumph die, like fire and powder,
Which as they kiss consume: the sweetest honey
Is loathsome in his own deliciousness
And in the taste confounds the appetite:
Therefore love moderately; long love doth so;
Too swift arrives as tardy as too slow.
<罗密欧与朱丽叶> 第二幕第六场
