Once, a father of a teenage daughter was concerned because his daughter spend too much time on phone; and nobody else in house could use the that line. So, he got a solution, he had a new telephone line installed for her.
Two or three days after her telephone had been installed, he came home to find her stretched out on the floor with her feet on the living room couch and chatting away on the family telephone.Her own telephone was resting silently on her dresser. "Why are you using our telephone," he yelled. "Why aren't you talking on your own telephone?"
"I can't," she said, "I'm expecting an important call on my phone."
