I am very polite, listen to the spiel, say no thank you, say it again, say it again, and eventually I'm allowed to hang up. But that's mostly to counter the effects of those who just hang up, I mean, if I have the time, why not be nice, they're only working. If I don't have the time I say so, nicely, and then hang up. But most of the time one of my 5-year olds will answer the phone anyway, and half the time they hang up and if I ask who it was they say Oh, they didn't want to talk to you, so I assume it's a telemarketer getting off the phone. I tell you, having a small child to screen your calls is better than an answering machine, I don't even have to delete after!
