I have very bad habits. Like Enamo, I space out. A whole lot. It's mostly because of lack of sleep though, if I concentrate I can snap out of it. Since I'm lazy and think of nothing but sleep, I usually don't. :V
When walking around, I usually use the same routes all the time because if I don't I would probably faint or fall over or something. My body relies on memory, you see. Where I've walked before, how I got somewhere, I don't usually think while walking on the way. I only think of the route I need to take then I just go there, hoping I would magically get to wherever I need to go. If I used a different route there's a high chance I would uh... fall asleep >_> I don't know how that happens, it's just.. when I'm somewhere unfamiliar I get suuuuuper sleepy. That's why I make it a habit to explore places when I've gotten enough sleep, otherwise I would fall asleep somewhere at an unknown corner.
Anyway, one day when I was at another school to represent my school for general info (some kinda small quiz shit whatever, I didn't get to answer any of them in the end so ye), and I was trying to remember where I was going but since I wasn't looking ahead, I lost my coach. Hah. It was horrible. I was at an unfamiliar school, and was about to pass out. It was right before that exhausting project we had too so I had 0 motivation to do anything let alone stay awake. So I passed out. :^D I was sitting down and there was a table right in front of me, it was great. I woke up to the sound of students exiting their classrooms to go have lunch. It was funny, they kept looking at me.
