今天聽一個老美同事說了一個習語:step on somebody's toes 和大家分享。
就是別人本應負責的事情,我們最好不要介入(Do not step on his toes。)
step on somebody's toes:to say or do something which upsets someone, especially by becoming involved in something which is their responsibility
eg. I'd like to make some changes to the working procedures, but I don't want to step on anyone's toes.
