It's a bit of a weird situation. We have a silent phone number (for which we've never been charged the $3 a month, by the way) but we still get a couple of telemarketers who have our phone number - thanks, I think, to my mum who gave my number to "trendwest" who have since changed their name to something else.
They're just about the only people who call us on our landline. Well, I think it's them - someone has been calling us several times a day for the past fortnight at least - we pick up the phone and there is a very long silence and then - if we wait long enough - someone for whom English is not their first language asks for one of us. I won't say my surname* but it has a couple of Es in it, which they stretch out.
Anyway, I'm reasonably polite to these guys, since they're making $1 an hour in Bangalore... I just found myself saying "Anyway, I'm not interested, thanks for calling, bye."
How polite are you?
*I'm still pretending that I'm untraceable, although my blogger nickname and my flikr logon and all of the hints spread throughout this thing mean anyone could find me... since this blog has a post that links back to my old blog which is technically illegal under Australia's sedition laws.
