I’m baffled that you wouldn’t know that it was somebody else’s apartment. You wouldn’t notice that EVERYTHING is different? Even in the dark you should notice that the apartment isn’t yours. The only excuse is to be so tired that you don’t know your own name. I figured that would be the defense, she slept very poorly the night before or she was working a lot of overtime. Her lawyer must be some disillusioned old guy that was only showing up for a paycheck, I’ve seen those lame-asses before (DUI lawyers in traffic court).
As it turned out, she wasn't very tired because she was "sexting" her partner (who also was her lover) minutes before she went into the wrong apartment. That seems to be the real reason she was distracted.
