Very good answers so far.
Now. Say for instance you sit in a plane, and let go a silent fart. When the guy next to you looks at you in disgust. Will you look back and frown in disbelieve that someone good fart on a plane, or do you shyly acknowledge that it was you and apologize?
Everyone that said to always tell the truth, what would you do now. Lie or tell the truth and be known as the stinky ass on flight 523?
