Its none of the delivery boys business whats in your package. Tell him its a big botlle of mind your friggin busines buddy. Kidding aside if you are uncomfortable and don't feel like telling the fed ex guy to keep his nose out of your bees wax than tell him its viagra. Oh wait that might be embarrassing to. Tell him its your diabetic meds, or whatever. Don't give others the power to control how you feel. Ya know?
