people part 1 continued

People who pretend to know everything about a certain subject, yet when asked about it they have no idea... there was a boy in my math class doing a presentation on angles, points, and lines. He was using Japanese hiragana as examples... BUT he wrote them wrong, in the wrong order, and sometimes not even the right characters! And he still claims to know them all! People like this dive me mad because they don't understand that people can see through their facade and know they are idiots.
