I have a cell phone also. In fact, it's the only phone I have! I was paying for a home phone but I was never home! All it did was take messages for me really! Now I have caller ID and voice mail on my cell phone. I don't always answer it but I do always have it with me, either in my purse or the car but it's always nearby. People get mad sometimes when they call me and I don't answer but the way I see it is this: The cell phone is for MY convenience, not theirs! Just because they felt like calling me doesn't me I am willing or even able to answer the phone. And I'm certainly not obligated to answer it!!! I pay for voice mail for the caller's convenience. So leave a message and I'll get back to you!
Here in NY, it is illegal to talk on the phone while driving though, because they say it's distracting. Which it probably is. But so is the radio....Anyway, that is my biggest bad habit. I think of so many things I have to say in the car! I'm forever throwing the phone down on the passenger seat when I pass a police officer. I miss half of my friend's conversations sometimes!
