I refer to my CW as bipolar because her behavior fits the description of the disorder. One day she came in pretty chipper. Within 10 minutes she was agitated and saying she had to go home because "this place is toxic" when not one person had said a word. She can be happy, pensive, nervous, pissed off and raging at one or more of us and back again all in the course of a couple hours. Sooo after about a week of being her target, she's now done a 180 and has been as sweet as pie to me for the past several days. She even brought me coffee and a pastry. This reminds me of my mother, who was in fact bipolar, who would beat the shit out of me for no reason, and then buy me something expensive to make up for it.
