“Like this book, the dictionary shows you that the word "nervous" means "worried about something" -- you might feel nervous, for instance, if you were served prune ice cream for dessert, because you would be worried that it would taste awful -- whereas the word "anxious" means "troubled by disturbing suspense," which you might feel if you were served a live alligator for dessert, because you would be troubled by the disturbing suspense about whether you would eat your dessert or it would eat you.”
