If our phone was any smarter or younger we could always just set it to mute in the evenings because it's never going to be anyone we want to talk to. I don't want to buy life insurance, sell my home, donate to dying kiddies, or change my electricity company. Believe me folks, if I wanted to do any of these things I would phone you.
Or, more likely, I would find a webpage and sort it out for myself. I'm not entrusting anything to the sorts of people who think that my evenings recovering from the day by lolling on the sofa are a fine opportunity for them to practice sales techniques.
If I hadn't been raised any better I would tell all you telephony people to go away.
