People combine caller ID with cell-phone melody rings to know who’s calling. They have fun picking a melody for each regular caller. I think we have it backwards.
I should pick my own unique melody, and everyone I call should hear the ring I choose. “But they’ll all pick Pachelbel’s Canon” you complain. Not at all. People who have trouble choosing their unique ring will consult a Ringtone Guru, who will study your personality for an hour and design a unique ring that is truly you. If you’re feeling flush, you can pay extra to buy additional phone melodies that express your current emotions. After all, mobile phones will soon have mood ring interfaces to warn the person you’re talking to how you’re feeling.
