Unidentified caller: Hello?
Me: Hello?
Unidentified caller: Hello?
Me: Hello? Yes?
Unidentified caller: Hello?
Me: Hello?
Unidentified caller: Sorry wrong number. (hangs up abruptly)

So you've dialed the wrong number. Does that instantly turn you into a deaf retard? Because it seems to have that effect on nearly everyone that dials my number in error. They simply cannot wrap their brains around the fact that it's not the voice they were expecting. How long should it take to process that their finger pressed the wrong button? .0011 nanoseconds?

Also people get very upset when you dial them accidentally. That conversation usually goes something like this for me:

Them: Hello?
Me: (very politely) Oh I'm sorry I've dialed the wrong number. (very politely)
Them: (GROAN!! HANG UP ABRUPTLY!! MY LIFE SUCKS!!)

Are you so disappointed that you can't even squeak out a little polite little something like "no problem" or even "OK"? Did you think it was the call that was going to change your life?

That call is never going to come buddy.
