How do you handle phone calls from telemarketers?
TM: Hi, is (insert butchered name) at home?
Me: No, I'm afraid she isn't, can I take a message?
TM: No, there's no message.
Me: Okay, have a nice day/night.
I'm pleasant, but if you're not willing to leave a message, then I really don't want to talk to you. If I'm feeling crabby, I'll let it go to my voicemail.
