I Am An Introvert

I remember when I was in high school a few years ago. During my senior year I had to write several essays and I always hated it when I had to use the computer lab because someone would always sit next to me eventually to use a computer. One morning before first class, I had a brilliant idea (at least to me)! I took out a sticky note or note card and wrote "Out Of Order" or "Does Not Work" with a bold black marker and stuck them onto the screens or keyboards of the computers next to me. Why hadn't I thought of that earlier? No one ever sat next to me again (except one time when someone found out my tick). I was at peace and could work on my essays in peace and quiet.
