Answering Machines

I believe Seinfeld did a bit on this (actually, I think his bit was on the word 'over' at the bottom of a handwritten note's first page, but let's just say this is the updated version)....

Do we REALLY need an explanation on what to do when one reaches an answering machine?  REALLY?  Is anyone out there, living in a civilized society, confused about 'wait for the beep, leave a message'?   Is there anyone out there who uses a phone who doesn't already have experience dealing with these things?  I can't imagine someone having a moment of 'ah?!  so-and-so isn't answering, but this thing is - WHAT do I do now?  I want to leave a message, but I'm just not sure how.'

Please let me know if you've ever experienced said moment.
