One thing that, for some reason or another, brings me constant embarassment, is the fact that when I was in middle and high school, I would frequently make ridiculously elaborate borders and decorations on my papers. I'm sure this all stems from my love of doodling. I would add window frames (like, icons, min/max buttons, resize handles, etc.), geometric shapes, shading, draw little pipes connecting different parts of the page, and so forth. This must have looked so silly.
