Where's ...Mr. Brown?!??

When I'm not enjoying country cruises, lightening storms, and being amazing at Etch-a-sketch (-ing?), I work at a coffee shop in a neighbouring town. My co-worker and I have decided that the town we work in is very much like Starshollow from the T.V. show Gilmore Girls. The reason we have come to this conclusion is due to all the quirky people who either work with us (including ourselves) or come in for coffee and a bite. Mr. Brown, Margarita Chicken Man, The Muffin Man, Luigi , and Yellow Jacket Staring Lady to name a few. This turns what could be mundane into a whimsical, hilarious place to be. Mr. Brown comes into the shop every week day around opening (6:30am) and leaves just before the lunch rush; he and The Muffin Man have become friends and will now sit at adjoining booths so they can talk while they enjoy their breakfast. On Monday, Mr. Brown's nephew came into the shop and asked my co-worker if she had seen him. The nephew went on to tell her that every once in a while, Mr. Brown will go M.I.A. for a few days and no one will know where he went. This started a whole new mystery with an air of excitement for us behind the counter. Where does Mr. Brown go??
