Walk from school to home the exact same way, following the same route, turn on my computer, and open 2 windows with 4 tabs on each to the exact same webpages as always, go downstairs for a drink at 5:30 p.m., finish my drink between 5:30 and 6, dress up the exact same way, lay out my iPod, glasses, watch and kindle the exact same way before sleeping, reading and listening to music before sleeping, set my plate and silverware the exact same way, wake up at the exact same way each day, bathe at certain hour when it's weekend, and at another hour when it's schoolday, have my cushion the same way, if not I'll feel uncomfortable sitting down on it,and many more things. Curious thing is that for some of them I don't follow the exact same order, however, the result needs to be the same, (i.e., arranging things before sleeping, I don't follow the same order, however, the watch and glasses need to be on top of the kindle in parallel lines, while my iPod has to be on the side of the kindle, if not I can't sleep), if not, I'll feel strange throughout the whole day. However, there're things that need to follow the exact same order, if I miss a step, I'll start over again (i.e. when dressing. I need to put on my pants first, then my shirt, then socks, etc., if I miss something, I'll start all over again.) And music, I'll repeat one same song over and over again, I'll listen to one same song when I dress, and to a different one for when I read before sleeping.
