I'd say just make sure not to take things personally. But upfront; don't play any passive-aggressive games, ESTPs don't like that very much. And also be prepared; an ESTP will probably be in-your-face a lot, and sometimes they will exhaust you. Make sure you set up boundaries so you can take a break if you need it, and don't get too defensive or moody, or else you will make them moody as well. And ESTPs can get quite moody if you press the right buttons.
