I've flagged this answer as 'low quality' because it has no sources and the way it is phrased, the author of said answer seems unsure of what he/she is saying. Here's the full answer, which I'll try to breakdown and explain why I flagged it:
Well i thought in most counties they dont say weekend instead they say holiday and in japan i thought the week is six days long only sundays (holiday) is the day they get off hence Miss All Sunday (All Holiday)
Follow up comment of his/hers when asked to elaborate:
I dont really know anything thing about other countries work week but i have only meet someone from napal and heard mention on a netflix from a (trevor noah) special
- Well i thought in most counties they dont say weekend instead they say holiday... I don't know how it looks to other people but for me, this is an assumption without mentioning the basis. He/She assumed it immediately as true and concluded this might be the case, without presenting anything as support. If the sentence was phrased like 'I thought that this is the case because I read/saw in this particular reference that...' or something similar, it would not be so.
- in japan i thought the week is six days long only sundays (holiday) is the day they get off hence Miss All Sunday (All Holiday) Again, another assumption that 'Sunday' is called 'holiday'. Also, a week can never be 6 days, unless he/she is referring to the days where you work.
- I dont really know anything thing about other countries work week but i have only meet someone from napal and heard mention on a netflix from a (trevor noah) special This entirely contradicts his/her answer. He/She first mentions of what he/she knows about other countries' work week then later on admits he/she doesn't really know anything and that his/her basis is someone from Nepal (not from Japan, which is what is in the answer) and 'heard mention' from a Netflix show without mentioning the exact episode.
- The previously accepted answer already confirms that this is not a holiday but rather, the mangaka himself stated that it refers to the happiest events, not necessarily holidays, of the year. The question is about One Piece and the mangaka himself answered the question. There is no better source to clear up misunderstandings or questions in the manga than the one who made it himself/herself.
Some might argue that the low quality flag can only be raised if the answer is not salvageable, and that it can still be edited. The formatting and grammar can be edited, yes, but the main idea of the answer was already contradicted, and by the mangaka himself. Isn't an answer that is already proven wrong by a reliable source (in this case, Oda) not salvageable anymore? I hope someone can enlighten me. Peace.
Note/Clarification: This is not an attempt to insult the one who answered the question or to the one who declined the flag. I am just trying to clear things up because this particular matter confuses me, that's all.
