-If a Facebook post actually makes me laugh (which is rare), I have to 'laugh react' to it. Same goes for comments.
-If hear footsteps behind me that sound too "aggressive", I must immediately assume they belong to an assassin who's about to jump me; and I must walk as fast as I can (but not fast enough to look suspicious) until there's a door between us, and then run like hell to my destination. And no, I don't watch too many spy movies, I'm just paranoid~. ;9
-If I laugh, I must cover my mouth with my hand. I actually didn't realize how automatic this was for me until recently...it's not a hard and fast rule, though; sometimes if the humor is surprising enough, I won't bother. ^^
-If I'm taking an exam, I must periodically cover my mouth with my shirt collar like I'm pretending to be a ninja. I...have no explanation for this.
-If I'm watching something, I must also be doing something. Either eating (if I'm watching something I've been really looking forward to) or working, on comics or homework (if I'm watching something I feel casual about). I can't just...watch things...
-I must plan each day's outfit according to the weather, the temperature, how active I'm going to be, and, of course, how stylish I feel~. I feel like this should be more common than it is...
-If I enter a room in a public place, I must sit in a strategically-advantageous place: somewhere with a clear view of the rest of the room, especially of the exits, so no one can go in or out without my notice. Preferred spots are near walls, corners, or pillars. I do NOT sit in places where I have my back to other people if I don't have to. Again, just paranoid~ ;9
-If I start playing a song and "don't listen to it well enough", I must start it over and play it again.
