To each his own- (via English - The Real Deal)

To each his own

To each his own，意思是“不同人有不同看法/品味”，换句话说，就是“青菜萝卜，各有所好”。如果碰到喜欢争论或者喜欢把自己的意见强加给别人的人，to each his own往往是最好的回答。比如：

A: Are you kidding me? "House of Flying Daggers" is boring as hell! "Meet the Fockers" is so much better!（你没有搞错吧？“十面埋伏”闷死人了。“拜见岳父大人2”好看多了!）
B: Well, to each his own. （青菜萝卜，各有所好。）

现在这个年代，什么都讲究PC（politically correct），所以to each his own偶尔也可以说成to each her own（如果跟你看法不同的是位女士）。当然，还有很多人说to each their own，一来足够PC，二来省掉了区分性别的麻烦。类似的用法在英语里已经越来越普遍。比如，“每个人都有自己的目标”以前可以理所当然地翻成“Everybody has his own goals”，但现在就更多地被翻成“Everybody has their own goals”。这种趋势很值得注意。
