Prejudice

OK, I admit it is my prejudice: Whenever I see someone typing Chinese characters and making an obvious mistake between "zai (在)" and “zai (再）" which in most cases is not a typo, I would think that is a demonstration of lack of good education, a so-called low-level indicator. Every time I see them write that way, it almost drives me crazy, especially when it comes to cases involving my good pals. I don't know why I've formed such a notion. I just think that is something very basic that everyone should learn well in his or her maybe kindergarten days, though I admit there are a lot of Chinese characters I can't name or tell the difference correctly.
