Is there a difference between 连朋友都没告诉过 and 即便是朋友也没有告诉过? Comparing Toosky Hierot's answer to my original attempt in Writing critique request: Zhou Ziwang loses weight, just like everyone else nowadays, we have:


  me: ...连朋友都没告诉过...
  Toosky Hierot: ...即便是朋友也没有告诉过...


I think both mean:


  Even [my] friends, [I] did not tell.


I'm not sure if there's any difference here, aside from perhaps writing style.  We've opted for different grammar constructs: 连...都... vs. 即便...也... which I think is the same as 即使...也... (which seems to necessitate the 是).

Question: Is there a difference between 连朋友都没告诉过 and 即便是朋友也没有告诉过?
连朋友都没告诉过 = Had not told even his friends

~

即便(是)朋友也没有告诉过(他们) =  Even though they (are) his friends, he had not told (them)

Notice:
即便 means &quot;even though&quot; or &quot;even if&quot;
There's a verb &quot;是&quot; (being) in &quot;是朋友&quot; (being friends)
More example:

连他父母也不知道他是同性恋 = Even his parents don't know he is gay
即便(是他父母)也不知道他是同性恋 = Even though (they are his parent), they don't know he is gay

Example of 即便:

即便(有)朋友也不能告诉(他们) = Even if/ even though he (has) friends, he can't tell (them)

~

即便全国警察都来了也救不了死去的人质了 (Even if) the police of the whole country were here, the dead hostages could not be saved.
