I second FLYBY's comments.
My 2 cents worth; Situational awareness + F'n common sense - there's also an apparatus in your aircraft, usually you'll have 2, they're called radio's - don't be afraid to use, if necessary take controll of the situation i.e. I'll be at 1000', confirm your intentions!
Re IF exposure, Flyby, simular experience just the other day - R/H seat first real approach. If pax new, they'd be mortified.
