My wife often has trouble communicating with me. She uses vague language when making requests. "Get me that thing" she says. I ask "what thing"? "You know, the thing over there." "Do you want the remote control?" "Yea, thats what I want." "Well why didnt you just say 'get me the remote'"?
It is a habit i have been unable to break her of. So I tell her, tell me exactly what you want, mean what you say and say what you mean.
