It must be a "sign"

Not an eight sided, red piece of metal that says stop. Not when you're thinking about your ex and your "song" comes on the radio. Not when you have a nightmare about a plane crash, deboard and then it crashes. More like... Dirty karaoke bar, one microphone, two people. The two stand uncomfortably apart as the "don't stop believing" piano solo starts up. The guy looks as if going to sing alone...."just a small town girl....". His partner (at the command of her shouting friends in the crowd "SIGN LANGUAGE".) She starts it up as well [arms only]. Nothing funnier than the guy belting it out as she struggles to keep up, laughing hysterically and almost falling from the stage flailing arms and all.
