Six calls in twenty minutes this afternoon alerted me to the fact that mum and dad were not seeing eye to eye.

The first four calls were from dad, informing me that mum was 'going absolutely, and I mean absolutely, berserk'. The next call was from Emma, their neighbour, to say that there was trouble at home. The last call was from Regan, who had been called by Emma, to say that there was trouble at home...

Meanwhile, I am trying to balance the financial predictions in a business plan due at the end of the week and can do without the constant interruptions.

I kept my cool with dad - he's pretty helpless when mum throws a wobbly. He said: 'Your mum's going bonkers. She keeps saying we're not married, and I don't know, I don't know what to do about it. I'd like you to come over and show her the marriage certificate and really put it into her head...'

I managed not to have to take the call from Emma in person, as I was still on the phone to dad at the time. Her message said: 'Your mum's just come over and she's really giving your dad a hard time. She really needs something to calm her down. I don't know if you want me to call the doctor. I tried to call Greg, but...'

By the time Regan called I was wondering what all this has to do with me. I cannot fix the problem. I don't really need to know about it. Pills - in which Emma seems to have unshakable faith - are not going to help. Dad feels better getting things off his chest, but his relief only lasts for a few minutes. He can't take advice and we've been on this merry-go-round countless times before. I'm just as helpless as he is.

Anyway, I later spoke quite amicably with mum, though she was obviously still very angry with 'him', without being able to articulate why. I know yesterday she took exception to the fact that dad was taking the wheely bins out, and caused such a scene in front of the house that people were crossing the road to avoid her (dad says). What the problem was today, neither mum nor dad could tell me. Perhaps it doesn't need a reason. The literature warns you to expect irrational and unpredictable behaviour - and that's definitely what we've got.

Now that I've finished my draft of the business plan and sent it off to the other interested parties I feel a weight has been lifted and I'm more able to laugh at what happened this afternoon. Unfortunately, I ran out of time to go over there, as I promised, but it seems both mum and dad have forgotten about this. I guess that's the silver lining.
