Britain's new Prime Minister Theresa May has officially moved into her new residence - 10 Downing Street.
But while former PM David Cameron has left, one occupant of the famous address won't be moving on.
Everything else was in motion, especially Mr Cameron, leaving office four years earlier than he'd planned.
"It's not been an easy journey and we've not got everything right," he said.
He'd got one big thing wrong - the referendum on leaving the EU, on which he gambled and lost.
So, he faced one last grilling in Parliament - a grilling that was more of a political stand-up routine.
"Other than one meeting this afternoon with Her Majesty the Queen, the diary for the rest of the day is remarkably light," joked Mr Cameron.
He laughed about the time he was stopped by someone on sidewalk in New York.
"Someone said, 'Hey, Cameron. Prime Minister's questions - we love your show!'", Mr Cameron quipped.
Ms May has run Britain's home office for six years, dealing with policing, immigration and other tough issues. She will now have to manage the toughest of them all - the divorce from Europe that she had actually campaigned against.
About the only thing that hasn't changed around here is Larry, the Downing Street cat. He's staying.
