The quickest and easiest way to earn my undying enmity is to call me Sashy or Sandy if you're not entitled to do so (these are the names my parents, my sister and my matrilineal relatives call me by). My sister's friends all call me Sandy. I will never get used to this, nor, it seems, will I ever cease to resent it. Rather unhelpfully, their calling me this automatically lowers my opinion of them below the point at which I would deign to correct them, which is endlessly stupid and counterproductive, but whatever.
