If I were a 19 year old boy (which I am, trapped in a 49 year old female's body), I would want some cool computer peripherals, an mp3 player, cool stuff for my car, books, subscriptions to magazines that I liked, comfy floor pillows that I could toss around and lay on when I played video games, a new turbo-type controller for my video game system, dvds of my favorite movies, a big basket of yummy snack food, jerseys of my favorite hockey or football players, tickets to concerts or sporting events, nice colored pencils and paper for doodling and sketching, cologne, rock posters for my walls, hair stuff (for that all important bedhead look), and a beautifully framed picture of my girlfriend that I could look at whenever I wanted to ;)
