Okay. Wow I can't believe this got posted! So anyway, I do this at home. Like before I go to bed I HAVE to make sure the two doors that lead outside are locked and that every cabinet door in the house is closed. And I probably do have OCD, As I have anxiety and Severe depression to boot as well. For those wondering: I didn't get up and close it for a few reasons. 1.) I didn't want to interrupt him. 2.) I figured he would find it rude and stupid to just get up and close a door that probably only bothered me. And 3.) I have anxiety, so getting up or even speaking in a class full of students is damn near impossible. Also, all of his lectures are also on Momentum (Which is basically how we email our teachers and get all the material we need for the class like the syllabus and shit) so I've already looked over what he taught for today. And to the person who said "i would not do anything, because im not compulsive about minor things like that." That's fantastic. Why don't you give yourself a pat on the back? I live with and am stuck around people who see that as "minor" and don't do anything about it. I know what a "normal" person looks like. I can't help it. I know it's minor, and i know that i shouldn't worry about it or be bothered by it. But I literally can't help it. So forgive me for being different. Thanks to the person who made the "Close" joke. OR if you were even making a joke. Regardless, i found it relatively funny and it made me giggle.
