Tune in to Body Language: Pay attention o other people's body language and non verbal cues such as limb movement, body positioning, head tilt, voice pitch, gestural mirroring, etc. If you see the person you are talking to agreeing with you but continuously fidgeting with any object, chances are that either something else is worrying him at that moment or that he/she is ill at ease with the direction of the conversation. You can easily interpret a person's moods and impression of you by paying attention to his/her tone when they are speaking to you.
