How to Lie to Your Players and Get Away with It...

A little tip for today: If the players catch you lying a once, they won't look for another lie at the same scene. Sounds strange, of course, but to my experience it is true. Players come, for some unknown reason, with the confidence in their ability to know when their GM is lying to them and when the GM isn't. If they catch you lie, as little and as unimportant as it may be, they will trust themselves even better with their ability to discern lies. This enables you to lie big time without them knowing it, or even suspecting it.

Don't overuse it, of course, and don't emphasise that you're lying 'cause they can still get suspicious, but if used lightly, it can invoke miracles at the right moments. Trust me about it, it works...
