If such sense were truly common, there wouldn’t be a Merit to represent it. Still, you have a gift for thinking one step ahead and assessing the potential consequences of your choices. Essentially, this Merit gives you a Get Out of Doing

Something Stupid Free card; whenever you announce an ac­ tion that wouldn’t be especially bright (for example, throwing a Time-Sphere spell at Old Man Wrinkle), the Storyteller may ask, “Are you sure you wanna do that?” Thus warned, you’re free to ignore the advice of your smarter angels. Still, you do get a momentary insight into potential dumbassery, which is more than most people get. Use it wisely.

You have an abundance of plain, everyday common sense (which is often not so common among humans or Garou). Whenever you’re about to do something counter to common sense, the Storyteller may step in and advise you that you’re about to do something that your character would recognize as foolhardy. This Merit is particularly recommended for novice players still coming to grips with the world of Werewolf and its dangers.
