During 4th Grade, my friend and I made a "business" that revolved around anything paper - comics, posters, trading cards, paper planes, etc. Our main provider of our paper frenzy was our school - we would grab as much paper every day when the teacher restocked. After a few weeks, our teacher deemed us the "Paper Wasters" and even began making the Weekly Paper Wasters Report, wherein he would report on the status of paper and how us Paper Wasters needed to lessen our dependency on the school's paper to a restricted amount per week (which we never followed). By 5th grade the "business" was pretty much done, though. 4th Grade was definitely the highlight of my school career. Back on topic, though. We loved making paper planes, my friend actually showed me how to make one during 4th Grade, and with the newly obtained knowledge I would spend every day at home coming up with multiple new models to perform various tricks (i.e. barrel rolls, back-flip back to me). I stored all of my models in cabinets in our basement, but it eventually got to the point that I had so many paper planes that they were overflowing out of the cabinets and onto the floor. My mom caught notice of this and shortly made me throw away every paper plane I had ever produced. Sad ending to some fun times.
