I recently same across this stumbling block in conversation; in one case I wanted to say "doesn't lift a finger" and in another "without lifting a finger". These phrases mean that someone is extremely lazy or selfish and refuses to help with a task or to do something.
In English these have a certain emphasis and connotation and I want to find something similar in Chinese so I don't want to use "他什么都不做" or "你什么都不用做". I am guessing there would be an idiom that I could use here?
