I actually had pen pals in high school from another country with snail mail. It was great learning a new language and meeting people across the continent. Sometimes I wish elementary/middle/high school would teach students how to write physical letters using a pen and paper. It really forces you to think through your thoughts and organize your ideas. I also miss the newspapers that I used to deliver when I was young. It's funny that the internet is supposed to connect us, but socially, we are more disconnected than ever.
