Skyrim? You get out of stamina by swinging one handed sword few times there

can't help but nitpick - it would be understandable if a couple was young and walked out to see who came. Old couples, or basically anyone who spent enough time together knows who goes to door and when

Brown skinned Ivan ?

even if you don't call the teacher by names, surnames and all that, at least his/her colleagues will

a teacher you see almost every day? I am bad with names myself, I can recount some history about a person I don't know names of, but not knowing a person who is in your presence almost everyday is really really hard

if my message came out as "mean" then I didn't mean it that way, but I can't see how it is possible for someone to be in the same class for more than one year and didn't even recognise the names of his classmates. Naruto is dense, but he isn't dumb. He is all about street smarts

was there such a restriction explained? I haven't noticed.

I don't in what kind of school you studied, but not knowing your classmates is almost impossible if you actually go to school. It is not like Hinata was in another class and not like he is skipping all the classes (iruka wouldn't allow him, neither will Hiruzen).

they have been in the same class for at least four years. It should be six, if I am not wrong, but at least four

And the reason I wrote isn't because he did something supposedly not possible in a fanfiction of all places. No, I was pointing out how it wasn't explained properly where all that came from. He could reason that he learned a bit in another life, which helped him understand how to do that or something along the lines.
