This just happened 2 minutes ago. I pick up my phone to call a close friend that I was to have heard from by now.
Dial number.
Phone rings.
Friend answers.
ME: "Hey man, how's it going?"
FRIEND: (with a very stressed out tone in voice) "Terrible...I just lost my - oh crap - I have to call you back."

end of conversation.
Man, I hate it then that happens...
