Mumblings

He walks around the room, standing near others then moving on to look in the basket. Then he goes to the kitchen areas. All the time he talks in a low voice. People do not know if he wants to talk to them or he talks to himself. Even if someone talks to him he does not respond. When he walks around he mumbles some words even though there is no one there. He walks and talks in his little world. Every now and then he sits for a while and then starts walking again. All day he is busy.
