It is well observed by the artist how children narrow their lips when they are snide. There was a clip of finance minister of United Kingdom (George Osborne, Chancellor of Exchequer) on a morning TV program, meeting with elementary school kids. One tyke, 1st or 2nd grade, narrowed his lips and asked: how much is 7 times 8. This is where people make errors more often in multiplication table, the brat surely had many victims before, Osborne, a history major, was like an innocent chicken slaughtered by a tiny smart alec. The minister replied "As a matter of principle, I do not answer math questions. Few months later there was a story how his office made a wrong budget projection by erring by three billion pounds in applying a formula.
BTW, Osborne, a son of baronet who made money making wallpaper, would fit well in this manga.
