In order not to offend either of them, I prefer to sit on the fence.

　　为了不冒犯他们其中任何一人，我选择保持中立。

　　sit on the fence原来是指“在分家产的时候，骑在分割家产的篱笆上，不知应该选择哪一边”，现在这个短语常用来表示：“保持中立，采取骑墙观望的态度”。因此，当美国人说"In order not to offend either of them, I prefer to sit on the fence."时，他/她要表达的意思就是:"In order not to annoy either of them, I took a neutral stance on this issue."、"I'd remain neutral in the event so as not to displease either of them."。
