Did you hear something ?   Oh , it is my cell phone ringing . I set it in the vibration mode .   It is a good habit to set your cell phone to vibrate . It is very annoying to hear the loud and sudden ring tone in quiet offices .   You are right . Some ring tone is just terribly loud . You can hear it even in the next door . It is really a kind of distraction .   Maybe we can write a report to the boss to see what can be done .
