Your phone's ringing in another room.  You race around to find it (I'll admit, it's almost impossible to find anything in my giant mansion apartment), but by the time you do, it's too late.  They didn't leave a voicemail, so you dial them right back.

Ring....ring....ring....ring.


NO ANSWER!  What did they do?  Hang up and then immediately run away?  Drop the phone and then book it for the nearest train station?  You ignoring their phone call was the last straw and now they're standing on a bridge somewhere taking off their shoes? 

I DON'T GET IT.
