Hello everyone. The other day I watched this video https://www.youtube.com/watch?v=pJ-ItilfC_Q . When the interviewer asked people if they know Pewdiepie, more than a half answered 知らないです. The rest answered 知りません. I learned that the second answer structure is correct. Is the first structure slang? If so, can it be used to modify other verbs and verbs in other forms? For example, are 寝ないです and 寝たです both correct?

Does anyone know where I can download Japanese subtitle for Kuroko's Basketball Season 1? I'm looking only for subtitles files. Now weird links please. Thank you.

Double if/then conditional. どこのでも、どんなのでも、それが台所であれば食事を作る場所であれば私はつらくない。 I have no clue how to translate it. Any help please?

Tae Kim's Grammar Guide Question. Double Politeness Is Okay? 時間がなかったからパーティーに行きませんでした。 There was no time so didn’t go to party. What bothers me is that Tae Kim used a double polite form (I just made up this term). I think that the でした part does nothing and should be omitted. Am I right?

Tae Kim's Advanced Grammar がる Question Questions: 1. Could がる be used to describe something else rather than an emotion? For example: 'he looks tired/hungry/warm/muscular'. What's the difference between がる and the 'seems like' grammar (みたい／のみ)？ 2. What if I make a statement such as 'A tired man left a room' without using the がる grammar. Would it sound like a guess? Can I say that? The link to the grammar is here: http://www.guidetojapanese.org/learn/grammar/signs#Using_to_act_as_if_one_might_do_something
