During office hours do you switch off your cell phone, put it on vibrate, or change the ring tone? How about if you are in a restaurant and your cellphone rings, do you take the call at the table or do you get up and walk to an area where you can speak without disturbing other customers ? What about having a cellphone in the movie theater ? My system is if i am out with my husband socializing then i do not carry my cellphone he has his for emergencies. In my office, my cell phone ring tone is customized for family only.
