That other one is off the rails.
So a while back I'm at the office in the evening and had turned my stereo way up and my cell phone rings. I answer while in the process of turning down the stereo and hear a snippet of what the person said and thought it was a client. I then mute the my stereo and start going into status of the case, etc., etc. Person on the other end says "what are you talking about?" Without thinking who it might be I just say "who fuck is this?"
It was my 77 year old mom who had a cold so I didn't recognize her voice in that split second.
