两个人 A couple

两个人在一起是件很困难的事. 生活习惯的不同, share bed 的痛苦, 鼻鼾声的扞擾, 等等等等!
当一切都没问题时, 两个人的事,慢慢扩充到两家人的事了. 这种威力不小于癌细胞的扩展. 伤害力可导至身亡.
(It's very difficult for a couple to live together. It can be because of the different lifestyle, sharing of bed, the annoying snore, and so on. When these have been settled, the couple matters will be upgraded to two families matters. The effect is not smaller than active cancer cell's expansion. It could be very hurt, and it could become fatal reason.)

不信? 比如说, 男的妈妈不喜欢女的. 妈妈会拆散这对情侣. 男的缺不听妈妈的话, 使妈妈十分*伤心*. 女的也不爽起来, 说些难听的话, 使男的很*难受*. 男的成受不了感情, 与亲情, 再加上工作上的失败. 他寻短见.
(Say, a mother doesn't like the son's gf. The mother will think of thousand ideas to break up the couple. The son does not listen to mother, he made the mother very worry, and the mother then even hate the son's gf. The mother might say something very bad. This made the son feels very sorry and sad. He then cannot face the family and gf, and may be some of other pressure from work. He decided to end his own life.)

这是会传染到别处去的. 例如, 女的后悔说错话, 她伤心男的因此而死了, 那她也活不了了.
(This is spreadable effect. Again, the girl might regret that she said something wrong, and she is sad to see the love one ended his life like that. She cannot keep her own life like this. )

两个人到两个家人的初期到末期癌症......
(It's the cancer effect from the couple to the two families...... )
