I Hate Being Accused Of Something I Did Not Do

Oh dear. I was accused of doing something wrong although the person didn't plan how they wanted the task completed with me. So I did my task correctly but because I didn't do it how she wanted it, I was yelled at and accused of laziness and disrespect. I did everything with positive intent and a willingness to do everything right, which I did. But instead of getting an apology, her later excuse was that she was actually angry because she had a fight with her spouse. I am sorry to hear but that is not the same as an apology. She has been very petty for the past few weeks and has been insulting me in an attempt to get a rise out of me and so far it hasn't worked. If she is going to act this way, then that is her problem, not mine.

EDIT: And to make matters worse they unknowingly dropped a pack of frozen chicken on the stairs and left it there. Oh dear.
