Trash Traders

In a big city, nothing is lost forever. A deaf-mute homeless will always help you return the thing you need if you are smart enough to explain. Give away items as a clues, and maybe you will found all your loses.

HOW TO PLAY
You can't hear each other, but you can show/see clues.
As Passerby: try to explain, what you've dropped into the sewage.
As Homeless: try to figure out what your mate has dropped into the sewage.
