I don't really five a fuck how people type some people worked really hard to learn how to type like that, The reason people do type like that is because they text more than they type so they set their minds to automatically type like that ! ^_^
Yes, it is annoying when people type by pushing the buttons on the keyboard isn't it? The racket it makes is so distracting... Unfortunately unless you have a tablet, it's the only way, so we'll just have to tolerate it together ^_^
