Dot is vile to Ailz. For instance, in the car today she was telling us how much she dislikes the CD we bought her for her birthday. The only song she likes is the final track, all the other songs are wrong in one way or another and one of them is about happiness and that's the last thing she needs. At the time I listened to her dodder her way through the complaint and thought, "Poor senile old thing, one can't take this seriously." But afterwards I reflected on the content- divorced from the dodder- and thought, "No. Actually, that was poisonous!"
