What do you call someone who sends postcards? A postcarder? Well I think it is a wonder full thing. I actually think there is a group of postcarders around the world sending each other postcards. What I like about a postcard is that it has a picture usually of a place you haven't been to. Which is good in it's self. But also the postcard has a message on the other side. This message is open for anyone to read. A public show of acknowledgement. So thanks all you postcarders out there keep sending those little rectangular pieces of card.
