Keith has decided that when he is put in charge of running the country (!!), he will pass a law to randomise days of the week. This will mean that we will never know, until we wake up in the morning, what day it is. If we are lucky, we could have 3 or 4 Sundays in a row - maybe not so good if you have to cook Sunday lunch for the in-laws each day!
On the other hand, you could end up with 3 Mondays in a row, or a fortnight of weekdays and no week-end. Not so bad if you work weekends, of course.
What about a week of Christmas days? Fine if you're a child, bankrupting if you're a parent, disastrous if you are trying to diet.
If, like him, you are a workaholic and work 8 days a week, I don't suppose it matters either way, but it would make life a little more unpredictable. I could live with that!
