Most characters (and people) carry certain things around with them most of the time. A purse, a backpack, or just a pocket. What they carry around with them (or what they DON’T carry) can tell a lot about them.
I have one character who carries two pictures with him, one of a person and one of a place. They’re getting a little tattered around the edges.
Another character carries a wallet that doesn’t belong to him.
And the last has a key tied to a shoe lace and an old pill bottle that doesn’t have any pills in it.
What do your characters carry along with them?
