At least you knew when someone had hung-up on you.
With cell phones, you can be smack in the middle of explaining the most brilliant idea since t-shirts with built-in deodorant...and realize that you've been pitching your breakthrough concept to an empty line.
But worse than realizing the other party is no longer a witness to your discourse, sometimes you find yourself in post-drop limbo...unable to reconnect because either (a) both of you are furiously redialing or (b) each of you assumes that the other schmuck will call back any minute.
Here's a simple tip: the person who initiated the first call should reinitated in the event of a dropped call.
It doesn't matter if you think the other guy's phone is the culprit. It doesn't matter if you're on a landline and he or she is driving through the Everglades.
If you dialed, redial.
