My T hasn't ever got mad at me (though underneath it all I suspect she's been frustrated at times, understandably!) but one time she was re-enacting how she'd been 'assertive' with someone, and she scared the **** out of me: suddenly she wasn't the warm woman I know, and I never again want to see that side of her! Clearly, no one messes with my T. I wouldn't want to anyway, cause you know, she's awesome...
