I phoned Greg last night and we talked about stocks and ISPs. He then turned the conversation to a call he received from dad the night before.

That day, Sunday, Greg and Regan took their daughter Cassy and a feast of cakes and other items, over to mum and dad's place. Cassy is nearly eight, and is beginning to lose interest in the games she and mum used to play when she was younger. Mum just doesn't have the energy, inclination, or the mental agility to participate properly. Soon I expect a gulf to open up between them. However, the visit had been successful, and everyone had enjoyed themselves.

When dad called later it was, as Greg put it, to have a witness to the fight going on between him and mum. It was the same old scenario: she claims he is a stranger in her house and demands that he leaves, he reasons with her and refuses to budge, she gets so frustrated that she slaps him.

Dad and Greg talked for a while, with mum in the background arguing with how dad was reporting things. Dad then turned to concentrate on mum, putting the phone down without hanging up. Greg was thus able to listen in to about six minutes of mum and dad fighting.

Mum was vituperative and insistent that dad get out. Dad was driven to the point of telling her she was going berserk and would 'have to be put in a home'. This is quite at odds with how he claims to deal with mum, of course, and is a method almost certainly doomed to fail. Even though their voices were being raised, Greg could hear the sounds of someone being slapped - dad, I presume, at the hands of mum.

After a few minutes Greg hung up. It was too sickening to listen to.
