trouble
On the tram, a father, carrying his kid in a chest harness, looked at his hand with an intent that made him suspicious. Not that i thought he checked if it was in shape to start trouble, rather a caring manner, like he checked it for injuries. Turns out a Ladybug had chosen his hand as a temporal residence, he just wanted to keep it occupied, to release it into the open again when he left the tram.
It felt good to see other people do that too.
