Oh do I have a story to tell you.
In the 11th grade, I brought my Nintendo DS, original brick, to Japanese class because it was the last day of school and well, why not. I was playing with it when another girl lost her DS and accused me of stealing it, as I was playing my DS. Well about 3 hours later, and after a police search, it turned out one person who sat behind her stole her DS, and put it inside his locker. He was arrested after that, and I vowed never to bring my DS to school again. >.>
Another time I brought my PSP to school, actually more than once. Once on the last day of the 9th grade, and that's where I first beat Final Fantasy VII Crisis Core. Another time was after the Advanced Placement exams and we were done with classes so I brought my PSP and let a girl I really liked play it. We had a lot of fun and bonded...and now I've brought up bad memories of what happened with said girl when I asked her to the Prom...
In college...actually now that I think about it I've never brought any of my systems to my college the past 2 years I've been there. Then again that's a good thing since muggings are quite common at my college, and the crime reports are always so racially similar that everyone at my college jokes that they are the same people stealing everything. XD
