Nothing on his face says what he saw.
Lifeless bodies of children pulled from the ruins.
Tents full of the dead wrapped in white shrouds.
Buildings razed to the ground by the devastating force of airstrikes.
Mahmoud Badawi saw humanity bombed, burned and wounded.
"There are a lot of difficult situations," he says.
"As an ambulance driver, you get used to everything that happens. Whether it's hands, heads or bodies being cut off... we're used to it."
His ambulance rushes from one scene of destruction to another.

In a narrow alley in Gaza, he stops to pick up two children who have been injured in airstrikes.
A man approaches him holding a bundle in his hands. It's a badly wounded boy.
He calls a friend who is helping emergency services load the victims, warning him to pay special attention to the boy.
"Nasser, he has an open wound on his head."
But Mahmoud remains composed.
It is not that he is unmoved by all that he sees, but necessity commands him to focus on those who can be saved.
As he speaks to a BBC reporter, a rocket explodes.
"We don't have time to rest with all this going on. The situation is very bad. We will now try to locate the bombed area to reach the wounded and dead."
Asked what the situation is with the supplies of medical equipment and medicines, Mahmoud says seriously: "We are running out of everything."
According to Hamas health authorities in Gaza, more than 7.000 Palestinians have died in the past two weeks.
According to reports, about 40 percent of them are children.
The UN warned that nearly a third of hospitals and two-thirds of primary care centers had to close "due to damage from fighting or fuel shortages."
The UN says its fuel supplies are running low and "tough decisions" will have to be made about which services will be prioritized in the coming days.
Israel refuses to let fuel into the Gaza Strip, saying it could be taken over by Hamas.
He also claims that this organization is stockpiling fuel.
In Gaza, days and nights merge mercilessly into each other.
War is a constant and in this small strip of land - the total area of Gaza is only 365 square kilometers - it is everywhere.
Israel has ordered the evacuation of about a million residents from the northern half to the south.
He claims this is so his forces can target Hamas.
But Israeli airstrikes do not stop even in southern Gaza, where thousands of residents have fled.
Whether to run away; where to run; where to hide if you escape - every day and night in Gaza is filled with desperate choices.
It also means there's no going home safely for emergency workers.
When he is on the field and working, Mahmoud takes care of his wife and six children as much as they take care of him.
When the bombing is fierce, he tries to call them every hour. But the phones don't always work.
"Getting in touch with the family is very difficult. We barely have a signal so I can call and find out if they're okay or not."
Mahmoud worked diligently to raise his family with a strong urge to serve the society. He is proud of his children.
His daughter is studying medicine to become a doctor.
She is inspired by her father's work and her own experience of the war in Gaza as a child.
There is also a son who is a paramedic. And another who qualified as a teacher.
When night falls, there is a lull in the bombing.
Mahmoud pauses and stops between his ambulance and the pile of rubble.
He holds the stretcher in his left hand, waiting for the next emergency.
Adrenaline subsided.
He is motionless for a moment and his gaze is lost in the distance.
His eyes are filled with sadness at all he has seen.
