A man came up to one of the BBC team in Green Square, the centre of Tripoli. He offered a handshake. When my colleague obliged, he palmed the spent casing of a bullet into his hand. Then he walked away without looking back.
In Tajoura, which is a suburb of Tripoli, a man strode up, very purposefully. I thought he was going to say something. Instead he handed me a computer memory stick, turned on his heels and walked off.
The man in Green Square was, I think, trying to send a discreet message. He was saying don't let appearances fool you. The square may look quiet, but the city isn't calm.
In Green Square, a man was firing streams of bubbles from a brightly coloured plastic toy shaped vaguely like a gun.
The bubbles were caught by the breeze coming in from the sea and whirled away towards the battlements of the fortress that Colonel Gaddafi used a few days ago as the backdrop for a speech.
Tripoli is controlled by the regime. Even so, it is worried enough to have tanks on major junctions on the way in and out of the city.
The streets are fairly busy in daylight. If Tripoli's residents thought violent regime change was imminent they would stay at home.
But outside the city centre, it feels less stable.
The man with the memory stick in Tajoura was delivering evidence. His district is a centre of anti-Gaddafi protest. On the streets you can see the remains of barricades made by burning tyres, and buildings connected with the regime have been gutted by fire.
He wasn't the only one who's been giving us pictures in the last few days. BBC News
