Interesting comments, thank you!
We do like the 'witching hour' of 12.00 when we maybe have a glass of wine, but all this goes back to when the girls were at home. The 'regime' started because once, when we were all on holiday, they insisted that we all sat down with a glass and a bowl of bits and chatted, which was always marvellous! This continued and the 6.00 pm additional 'witching' hour began a day or so later, when we all made sure that we met up and chatted again!
So I suppose this is all down to habit, and although the girls have moved on down the road, Mrs Growster and I still make the two times the important parts of the day! I think, so far, that I enjoy the big meal at lunchtime, but this is partly because my old job entailed a lot of lunches, some formal, some disgraceful, and the haven of a home-prepared dish still beckons! Luckily Mrs Growster agrees...
We'll see how we get on anyway!
