you're involved with something engrossing, the mood is mellow and you have a few moments of time for just your thoughts, suddenly the persistant ringing of your phone, you don't want to answer it, but there's that...a guilt that it may be something important, you pick it up...and nothing, no sound, no breathing, not even a dial tone...just...silence...are they seeing if i'm home?!?!

does this happen to everyone that has a home phone, and who are they?
