The cell phone has made keeping in touch easier and safer. Now, the kids have instant access to a 911 operator in case of emergency -- which is probably the biggest reason you added them to your family calling plan in the first place. That cell phone has turned out to be pretty convenient all around. Now your daughter can call to tell you her music lesson is running a little long, and you can let your son know you'll be late picking him up at soccer practice. You can even call your spouse to ask him to pick up a gallon of milk on his way home. Yes, when the family is connected, life can be pretty convenient and happy -- well, until the cell phone bill comes due, anyway.
