There are two kinds of fears: rational and irrational – or, in simpler terms, fears that make sense and fears that don’t. For instance, the Baudelaire orphans have a fear of Count Olaf, which makes perfect sense, because he is an evil man who wants to destroy them. But if they were afraid of lemon meringue pie, this would be an irrational fear, because lemon meringue pie is delicious and has never hurt a soul. Being afraid of a monster under the bed is perfectly rational, because there may in fact be a monster under your bed at any time, ready to eat you all up, but a fear of realtors is an irrational fear. Realtors, as I’m sure you know, are people who assist in the buying and selling of houses. Besides occasionally wearing an ugly yellow coat, the worst a realtor can do to you is show you a house that you find ugly, and is it is completely irrational to fear them.
