You hold your head by the chin and slide open the glass. One of the heads opens his eyes and smiles at you. He is blond, handsome and has some chin stubble. He seems to be about your age.
"Hey. Welcome. Would you like to try on some of our styles?" he said.
"I tried. But my head won't stick." you say, trying not to sound desperate.
"You can't try on your own head. Here, put yourself down next to me and try me on." he said. He smiled a big salesman's smile. You put your head on the shelf and pick up the other head and put it on your neck. you feel a cool sensation on your neck and you move your hands slowly away waiting for the head to slip off.
Once your arm is out of the way, you see that the head has bonded to your neck. He turns and smiles at you.
