I carry a TracFone around with me for backup and emergencies. I don't give the number out for people to call me on or check it for messages. My home phone is where people need to call me if they actually want to get in touch with me.
I also use the TracFone to make long-distance calls. My home phone has unlimited local calling but doesn't do long distance, and the long-distance company adds a whole new layer of "fees" and such if I ever make a call with them (which I stopped doing after I got the TracFone). It's one of those do-gooder companies that supposedly supports all kinds of good causes with their revenue.
Recently I accidentally made a call on it, and I got a bill for more than $3.00, of which the charge for the actual phone call was about 20 cents. I called to complain about that bill, and they not only dismissed the fees, they dismissed the whole bill.
I meant," said Ipslore bitterly, "what is there in this world that truly makes living worthwhile?"
Death thought about it.
"Cats," he said eventually. "Cats are nice."
