Where is it?

Now, I think all my fellow nerds can relate when I say I hate losing assignment or anything that helps me to excel in school. Some might go as far as calling it some kind of phobia. Which is the reason way I am an extremely neat; to the point where some people may thing I have OCD. But I don't I just like things to be in a certain place, so I know where it is.
Here are some incident where I might have freaked out because I couldn't find something. Most of the time it was due to a fellow classmate playing a prank on me. One time it was even because if a teacher and I'm hoping I can find at least one person who can relate.
