During meetings at work, I have this constant fear that my cell phone is going to go off. I understand this to be a totally unfounded fear because I never have my cell phone with me in meetings. There WAS this one time when a lunch ran late, forcing me to run into a meeting without first dropping my handbag off in my office. I slid into the meeting as inconspicuously as possible and stuck the bag under the table, by my feet.
Yes, my phone did go off then.
The room was quiet.
My phone's ring tone--a slow, schmaltzy tune--wasn't.
So, yes, that's where the fear originates. It's still, however, totally irrational.
