互不认识英文

你要说的很凶的话，就是：Fine, we're strangers ever since!或者是伤感点：we're strangers from this moment.(从现在开始，我们是陌生人了。)

i don't know him/it

You and I were strangers.

although we don't know each other/

可以问得再具体些么。。不认识什么后面的名词不同 动词也不同哇我不认识你I don't know you.我不认识字I didn't read.

Even if we did not know mutually.

Since we do not know each other。
