Writing letters to your friends or loved ones used to be a common way of communication. Yet, as the world becomes more electronic or electrical based, home phone, followed by mobile phone came into our lives. I believe that the demand for paper will slowing decrease, hence saving the trees. Yet, I still find that receiving a handwritten card is more heartwarming than a text message from the phone, just like the postcard my relative received from her overseas friend. At the back of the postcard, it was printed “postcard printing from printingamerica.com.”
