Funny isn't it, how life, seemingly set in its ways, can change in an instant. I'm talking of course in a strictly Formula One sense. By all standards, last weekend's grand prix in Germany was distinctly weird. Lewis Hamilton was happy, really happy. Perhaps weirder was the lack of success for Sebastian Vettel.
Let's take Lewis first. He was grinning broadly before the race and whooping with delight when he took the chequered flag. Considering this column (and a lot of other commentators) was recently criticising the Briton for his demeanour it was something of a turnaround.
Hamilton is a born racer. Of course, everyone lining up on the grid is a racer, but few have the lucky combination of skill, aggression and a decent car to scythe through the field. For most of this season he's been scything into other cars and in Monaco he openly criticised his own team. He even appeared to be publicly courting Red Bull.
This week, though, everything is rosy in the McLaren camp. As the teams roll into Hungary, harmony is the word for the British. The reason for this love-in is simple - a fast car.
Give Hamilton a car he can win in and he suddenly becomes much more cuddly. He certainly had that at the Nuerburgring on Sunday. The unseasonably cold weather probably helped, but Hamilton's focus certainly did.
He said after the race: 'I was in a really very good head space and perhaps I feel even better because I felt the moves I did were some of the most precise moves I have pulled in a while.' It's when he channels his aggression that the precision and success comes.
So what of Vettel? It was all set up for him last weekend, the dominant car of the season driven by the dominant driver at his home grand prix. Instead, a fairytale turned into a nightmare. He rarely seemed comfortable over the weekend and his spin during the race underlined the problems that saw him off the podium for the first time this season.
