家家有本难念的经。

We all have our crosses to bear.

代沟是一个普遍存在的问题，每个家庭都有，正如家家有本难念的经。

Generation gap is a common problem, it exists in every family, just as every family has their trouble.

正如中国俗语说，家家有本难念的经。但我想说的是，有些“经”念起来也挺温馨的。

As the Chinese saying goes, each family has its own trouble. But I want to say that some trouble are sweet.
