-when you have to read a question/sentence/paragraph multiple times to actually understand it
-when a particular question has a grammar/spelling error and you have to physically change it to remain focused
-when your sitting in a desk paired with another desk in class and there is a slight crack between the two, so you therefore have to re-allign them together
-putting almost everything in order based on size, name, subject, etc
-continually checking my pockets/bag to make sure I haven't lost any of my belongings
-if I make a tiny mistake while writing something down, such as making lower cases look like upper cases, I have to erase it or start over
-whenever I'm turning up/down the volume, heating up food in the microwave, or the like, the number always has to end in a 0 or 5
There's likely a lot more that I can't think of... I'm not even diagnosed with OCD. Share your habits!
