Red Light Down White Light UP

I just got some soup at the cafeteria. When i was leaving I got in an elevator going down to the lobby. A woman got in the elevator with me. She meant to be going up. She was upset. "It's not a long ride" I assured her. "Yeah, but i"m going to have to see people" she said. "They're the worst" I replied. While true, this statement is pretty humourless. She laughed though. Then she looked at me really interestingly and kind of stopped smiling.
