That brings up a good point: answering machine/voice mail greetings.
OK - it's 2007. Answering machines have been out quite a while now. People do NOT need to ramble on about how to use the dang answering machine in their greeting!!! Example:
(Spoken slowly and over-enunciated) "Hello. You've reached the Smith residence. We can't come to the phone right now, but after the beep, if you'll leave your name, number, and a brief message, we'll get back to you as soon as possible. Thank you for calling."
DUUUUUHHHHH! I'm so glad you told me to wait for the beep and what to say. I wouldn't have had a clue what to do!!!
Also, I hate it when people let their little kids record the greeting and/or sing a song on the greeting. You can't understand them, so you don't even know if you've called the right number. It's not cute. It's downright annoying.
