DW and DD have been at again; too upset to sleep

[DisgraceToTheYChromosome]

This evening DD remarked that her phone wasn't working. She has another basic phone which works. This DW knows, or we (DD and I) thought she did. DW decided, without being asked to turn the house upside down at bedtime looking for a working phone. DD, meanwhile, had been feeling a bit gloomy as teenagers do, so like a sensible person had gone to bed. DW finds another phone, presents it to DD by waking her up, and then has a massive rant when she isn't immediately showered with kisses. DD was reduced to hysterical crying, ran out into the back garden. DW goes to bed in a strop. I get DD indoors, cuddle her while she cries herself out, put her to bed, and repeat the process with DW who is now saying that DD hates her, she's a rotten person, she's going drive the car into the river etc.
So I'm lying here with my blood pressure through the roof again. Grr.

"Id have told them to deal with it between them and fucked off to the pub"

They both sound like drama llamas. I wonder if there is some sort of power play going on between them?

Dw needs to be told that this kind of behaviour is not acceptable for a grown woman and she needs to get a grip, otherwise dd will grow up to be just like her.
