Can't Talk
Have you ever called someone and they answer the phone, whether their cell phone or land line, and after introducing yourself, they respond like this: "I can't talk now, can you call back in 20 minutes?"? Now I understand that people are not available 24 hours a day, even on a cell phone. However, if you can't talk, then don't answer your phone. Let it roll over to VM and call that person back.
Just a pet peeve of mine that I experienced today when calling someone. What is a pet peeve of yours?
