I remember that the days before computers, I had several pen pals while I was still at school. Mail from and pen pals was received with great anticipation and enthusiasm. Each time the postmen came, I was eager to find out if any of the mail was for. My penpals and I also exchanged post cards as well. Around that time, I also started a small stamp collection. Well those were the days. Nowadays I normally just received bills in my mail.
Yes, I remember pen pals also. It's amazing how fast the world has changed. Now I don't think twice about communicating online with someone halfway across the world.
Those were the good old days.
