Buying the perfect gift is an adventure that many undertake but in which few find success and even fewer can claim to fully master. This is because they don't bring the right tools. A stick and a rock? Yes, but the list cannot end there. Don't forget your daily essentials including but not limited to: a protractor and compass, extra orange traffic cones, "The Brother's Karamazov" hardback in Russian, a Russian to German dictionary, and your brother's bassoon, just to get you started. In addition to just simply loading up on the necessary tools, don't forget the training Old Master Pei Wei has taught you. The twenty years you spent in the jungle have prepared you for this journey; trust your instincts. Always remember, the hypotenuse of the 45-45-90 right triangle may be found without the use of your TI-84 Plus, but my heart will forever belong to you as long as you close your eyes and follow your nose. So whenever you feel lost and alone, just look at the North Star and remember me. And don't you dare close your eyes.
