I fought getting a pager for years. . . and then, when my girls reached teen-age I needed one for emergency purposes. I cherished my alone time in the car while driving, but alas, I had to give it up in case they needed a ride somewhere because their mother was not available. . . then my business required me to be available 24/7 and the pager was more convenient than my having to answer a phone to find out I really did not need to reply to THAT particular client right then. Some were of the assumption that their emergency was necessarily MY emergency, and EVERYTHING to them was an emergency, no matter how trivial or unimportant. I'd rather return their calls at my convenience than theirs.
Now we have our smartphones and voice mail. . . much better to listen to their voice mail to learn if I even ever need to call them back at all! Now I can listen, text them "See you next week, everything is being handled!" and ignore their emergency. The Triage abilities are much more convenient. LOL! AND much more peaceful.
