KEY POINTS:
For the first time since I'd been in Zimbabwe, on my way to work I passed two women busy sweeping litter and leaves from a street corner. It seemed a minor miracle, given that most basic civic services in Zimbabwe had broken down.
There had been no refuse
collection for months and the water and sewerage system in many areas of the country had stopped functioning altogether.
On this day, it seemed highly symbolic - a clean sweep.
It was a day which many Zimbabweans were praying would bring them change, after months of political deadlock, an ever-worsening economy, and a humanitarian crisis as the country battled its worst cholera epidemic and serious food shortages.
It was the day [last Thursday] Morgan Tsvangirai, the country's main opposition leader, was to take office as the country's Prime Minister in a new unity government.
Mr Tsvangirai won the first round of last year's presidential elections by a small margin. But he withdrew from the run-off citing violence against his supporters.
In September, though, he agreed to a power-sharing arrangement with Zimbabwe's President, Robert Mugabe. However the deal had been stalled for months, amid political disagreements.
While there are sceptics who say the new political arrangement is a sell out and unlikely to achieve much, many Zimbabweans beg to differ. They see the new political arrangement with optimistic caution.
Many told me things couldn't get any worse and that the formation of a new unity government gave them cause to hope again. They believed it could mark the start of change in their country, which has seen thousands killed from cholera - a curable and preventable disease - with up to seven million, more than half the population, dependent on food hand outs.
Later in the day, after being officially sworn into office, Zimbabwe's new prime minister addressed thousands of supporters at a packed showground in Harare.
Some attending told me they'd sold household goods - a TV set; an iron; some clothing - to get enough petrol to come to Harare to listen to Mr Tsvangirai address the crowd as the country's new Prime Minister.
He promised to end political violence and Zimbabwe's culture of impunity; to work for a society where people were no longer living in fear of reprisals or repressions for their views.
He said Zimbabwe would not be a pseudo-democracy, but a functioning democracy, where the rule of law could be re-
established.
A second top priority of the new Government, he said, was to tackle the humanitarian crisis, to stem the cholera epidemic that has gripped the country, and to ensure that those who needed food got help, regardless of their political or tribal affiliations.
He also promised to appoint a senior cabinet member to co-ordinate humanitarian efforts; to remove tax duties for humanitarian food aid and organise a food summit; and to try to ensure that in the future, Zimbabweans would not go hungry again.
Finally he vowed to stabilise the country's economy, which has been characterised by crippling hyperinflation; to reopen hospitals; to get children back to school; and to get civil servants back to work.
All music to the ears of the crowd and possibly good news for international governments who have said they will carefully monitor change in Zimbabwe before making serious commitments of financial help.
The crowds in the stadium cheered, danced and waved flags. Even a reporter from a government-controlled newspaper seemed happy.
He said: "We used to be dead. Now we are alive. This is the start of change."
