You mention how she's a lonely dried up over the hill woman who needs someone in her life because she's an unhappy person. So if she knows what's good for her she'll start treating you both with more respect. And that's just one of the things you say. Not that she isn't totally without ammo, but you feel actually energized by the battle. Like you're getting off on the conflict. Eventually you wear her down and she half-heartly gives in.

You know that your Mom is never going to be docile, but you've effectively changed the balance of power. You go to bed totally pleased by your vitory. Your confidence transformed into arrogance and finally into outright manipulative nastiness.

Another day arrives and you feel like Mom...
