Milka opened the door.

-Come in, he said. -Fast!

He looked down the street. Up the street. Then closed the door.

-Are you OK? Tanker looked at him with a worried frown. His friend had always been nervous by nature, but he acted strange. 

-I’m perfect! Milka guided Tanker in to the living room. -Do you feel it?
-Feel what? Tanker looked around the room. Suddenly he realised what it was. The treads were different. They didn’t tell him what to do. He looked at Milka with big, scared eyes. -What did you do?
