A lot of people were very angry when they learnt Dominic Cummings had driven his family from London to County Durham during the lockdown.
On the one hand, you had Boris Johnson and his Government colleagues telling the rest of us that we had to stay at home.
On the other, Mr Johnson's chief adviser was behaving as if was too important to obey the rules.

Now, the same thing has happened again.
We've gone through months when we were barred from seeing people we don't live with - including loved-ones such as family members.
In some cases, that meant staying away from a girlfriend or boyfriend. And if you did see them, you weren't supposed to hug.
But it turns out that the Health Secretary, who regularly appeared on television screens exhorting us to obey the rules, was breaking them himself.
Matt Hancock had a secret affair with his closest aide, and the photos make it clear they weren't staying two metres apart.
There are plenty of issues raised here. For a start, Ministers are expected to keep relationships with their staff on a professional basis.
But what hits hardest is the hypocrisy of it. Not everybody has obeyed lockdown rules to the letter, but a great many people really have, despite the emotional and sometimes financial hardship it caused, because they were told it was the best way to protect not just themselves but the wider community, and the NHS. Mr Hancock's behaviour feels like a slap in the face.
What's remarkable is that he, and Boris Johnson, thought he could brazen it out. On Friday, the Prime Minister was insisting he accepted Mr Hancock's apology, and the matter was "closed".
At least Mr Hancock had the good sense to see that wouldn't work.
Even after the Cummings affair, the Government remained relatively popular. The Tories went to enjoy an historic by-election victory in Hartlepool, for example.
And it remains to be seen whether this new scandal will dent support for the Conservatives, who could win another important by-election victory in Batley and Spen, Yorkshire, next week.
hat do you think about the resignation? Answer our survey
The fact that Mr Hancock resigned (unlike Mr Cummings, who stayed on until walking out of the Government for unrelated reasons) might help. And there's still a view that Boris Johnson and his team have done well to get so many people vaccinated so quickly.
But it adds to the impression that this Government holds the public in contempt - that senior members think the rules that apply to us don't apply to them.
It's a perception that Mr Johnson needs to dispel, if he hopes to retain support once the Covid crisis is over.
