I get loads of those every day. More annoying are scam calls. I have arguments with these people on a daily basis. I've been threatened by them on several occasions. I've told them before: You say you know my address and you've got my phone number, so feel free to pop around any time...
I wouldn't even pick up my land line if it were not for my grandparents steadfastly refusing to use or call mobile phones.
I listened to Sigur Ros today, did you?
