好朋友有親密無間的BFF（Best Friend Forever，永遠的好朋友），也有不那么坦誠的BBF（Best-Behavior Friend，好行為朋友）。你交過BBF嗎？

Best-Behavior Friend, also known as 'BBF'; a friend whom you have very little in common with and you act on your best-behavior when you're with.

“好行為朋友”簡稱BBF，指跟你沒有什么共同點的朋友，你和這個朋友在一起時，總是表現(xiàn)出最好的一面。

A best-behavior friend does not typically know the extent of your true character or transgressions because you misrepresent the truth to make yourself look good or innocent. A person with a best-behavior friendship may see the friendship as important or long-standing and so lying about situations or leaving out key facts becomes common.

“好行為朋友”往往不知道你的真實個性或離經(jīng)叛道的程度，因為你在他們面前表現(xiàn)出的是天真無邪的一面。有“好行為朋友”的人可能很重視這段友誼或者因為彼此相處時間已經(jīng)很長，在某些事情上撒點謊或者抹去一點關鍵事實就成為稀松平常的事了。

例句：

Meg got staggering drunk at the dancing party last night.?She?went for lunch the next day with her best-behavior friend Rachel and when Meg recounted her night to Rachel, the?drunk elements were removed.

梅格昨晚在舞會上喝得酩酊大醉。第二天她跟自己的“好行為朋友”瑞秋一起吃午飯，當她向瑞秋講起昨晚的事情時，喝醉的部分被省略了。
