paying attention (I do have a tendency to let my mind wander)
maintaining eye contact
When in an argument, try to stay to the point of the argument (if the argument is about leaving a door unlocked, don't suddenly point out how them twisting their hair bothers you.)
Watch your tone to make sure you aren't coming across as rude
Don't do anything that you know annoys the person you're talking to. (Ex: rolling your eyes, tapping your fingers, etc)
