Answer:
- 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)
I hope you found this helpful.
