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.
Good idea.
