It truly upset me every time I hit my head on that toilet room door! Why are the doors for the toilet rooms so short in Japan?! Of course, I was living in a pretty old apartment so maybe mine was just small. The other doors were taller in my place, still not quite tall enough for me, so it was difficult to remember to really duck down low to get in to use the toilet when half asleep. It's a good thing Tanuki ended the comic when he did, Karl was pretty "vocally" angry.
