In School Too Long

I am in the process of writing an essay for one of my English classes. When I went to save what I have done so far I found another essay already there with a similar name. Turns out, while I'm comparing two texts for this essay which is a totally different assignment, a few years ago I wrote an essay on one of the texts already. I did not remember at all, and it isn't even a short one. I went to go look for the hard copy to see how I did and what the prof had written about it. I went searching through all my saved notes but couldn't find it. (Turns out, now that I'm looking at the saved copy on my computer, I wrote it at the end of the year so probably never got it back.) In the process of hunting I came across a bunch of other essays that I didn't remember writing, a few even for a course I don't remember taking, with a professor's name on it that I don't remember having. This really freaked me out, so I started to look into this mysterious SOCI1010 that I guess I took at some point. I had no idea that I had taken a sociology course. It took me a while in the undergraduate calender to figure out that it was a first year Human Rights course I had taken a few years back, that I do remember. Also we were supposed to put our TA's name on the papers, so it wasn't that I had forgotten the prof, just I didn't recognize the TA. I really think I have been in school too long when I have written so many essay I can't keep them straight or even remember them but I guess that happens to everyone in the upper years.
