I got a tricky question today

My teacher asked me why I always sit at the same place (my favorite red sofas) near his office while studying. Well, what should I answer? For me it is completely natural to sit always at the same place, because I learn to ignore the distracting things quite fast.
The other similar places in the Paradise building are noisier and I don’t like sitting in the library for two reasons: 1. I already bought the books anyway. 2. It is like social event to go there. I always meet some friends.
And yeah, when speaking about the teachers at the 3rd floor...there is one more working in the same office. He always makes me smile. Not because he would be some extraordinary man, but because one of his shoes scroops. Yes, just one. It is so damn funny. On Monday evening, I was too tired to control myself and I just started to laugh at him, err, I mean laugh at his shoe (I never laugh at teachers!). And of course he noticed that. Oops, I hope that I will not meet him at some exam in near future. Or that he has a good sense of humor.

Oh, you think there is one more option! (Studying at home.) I thought about that as well. But what would I blog about then?

UPDATE: I forgot to mention why the 4th floor is not suitable as well. The vice-dean’s office is there. He is responsible for the student affairs and he is the guy with whom I solved my 4 or so situations when I was almost fired from school. Yes, I have the bachelor degree just because of his human approach to students. Now it always freaks me out when I see him. I don’t want to speak to him ever again. Makes sense, right?
