Here are a few helpful hints for the day from a little book I found recently called NANCY DREW'S GUIDE TO LIFE:

Don't hide in a phone booth. Someone could turn the tables on you and trap you in it by wedging a piece of wood under the door. ~ The Clue in the Jewel Box
Flowers sent by secret admirers might be coated with poison. ~ The Secret of the Golden Pavilion
When pinned down by a large canine, instruct friends, family, even random passersby to direct a hose on the beast. ~ The Mysterious Mannequin
You can tell a lot about a man by his hands. ~ The Clue in the Jewel Box
Come up with a clever code with your beau in case one of you is ever kidnapped. ~ The Invisible Intruder
After receiving an electrical shock to the system, find as many men as possible to vigorously massage you. ~ Mystery of the Glowing Eye
Don't say "well" all the time. It's far from well. ~ Nancy's Mysterious Letter
Well.
