Lex opened the door to his apartment and heard a noise. He stopped as he looked around and found nothing.
"Weird! Am I hallucinating or what?" Lex thought and then opened the door fully. Once again, the noise came, and Lex was now sure he wasn't hallucinating. He had heard the tuning of a Guitar.
He looked above him and found a guitar pasted on the ceiling; along with it, a small stick with a chip on its tip was pasted on the door.
It was done in such a way that every time one opened a door, the chip would brush past the guitar's strings, producing a smooth and soothing melody.
Lex smiled and began to move the door back and forth as the melody filled the apartment. He liked it.
The melody alerted the residents as Lex heard some footsteps rushing in his direction. He smiled and opened his arms wide, waiting for something.
But no one hugged him.
