My friend believes my mom is ESI, and it definitely is "her way or the highway." She is extremely stubborn. My dad also always wants to help her with different things, and she won't have it. She does real-estate, and she is super busy. He constantly offers to help, but she refuses to let him, and seems annoyed even by the gesture. Then again, my dad is extremely chatty and she may not want him to say the wrong thing or screw something up. I'm not sure what my dads type is, but he's a great salesman and is very personable.
