This morning there were three missed calls on my cell phone. I am not one of the people walking around holding a cell phone to an ear or driving while trying to negotiate traffic. I don't begrudge anyone who uses a cell phone most of their waking hours. My lifestyle is different by choice.
To the best of my recollection, people used to use etiquette on the phone and this was taught to children in beginner telephone 101.
In the past, if I wanted to know if I missed a call I would install an answering machine to the home telephone and that way someone could LEAVE A MESSAGE. What a unique concept.
When I see the orange blinking light on my cell phone, I know I either have a message or there was a missed call.
If there is a missed call, I console myself with my standard approach of "hey, if it were important, they would LEAVE A MESSAGE".
