How does this happen? People do it all the time, and I can't help but wonder, doesn't it take more effort to press down the shift key before every word than to just do it when necessary? People say it became a habit, but how does such a thing start? Some people say they even learned how to type that way and it makes me think about how odd that is.
Can I get some explanations from people who've done this, or are even doing it now? Maybe just a few guesses from people who don't?
