The Meisner repetition technique is such a powerful method of teaching this.
The technique has two or more actors repeating the same lines back and forth at each other, based on simple observation and repetition. But what's really being said and communicated is the subtext of how the actors sense and feel - not the words at all.
Saying "you're wearing a blue shirt" might encode the thought "I don't like the tone of your voice" or "you've got a nice smile." And the other actor is meant to read that off of you and respond in kind.
