Do you know what a penpal is? Remember the term 'penpal'?
Years ago in a New York City public school, my 4th grade teacher had our class exchange panpal letters with another local school.
In high school my French teacher had our class write to French students in France. We even had to write in French and our penal had to answer in English. My French dictionary was very handy.
Today's technology people use Facebook, text, Twitter and e-mail. I still believe in the art of letter writing because it is more cordial.
