My boyfriend and I run our cleaning business from his home. He had just installed a cellular phone in his car so he could make calls while on the road. Excited with his new "toy," he called me for the seventh time that morning to ask if there were any messages for him. "No,Bob,not since the last time you called 10 minutes ago. " I replied tediously, wondering when the novelty would wear off. I hung up and, to my surprise, he walked in the door. He had called me from the doorstep.
