When I was young I had a pen-pal, who was just my primary school best friend separated at high school. We use to write to each other on cute stationery even though we lived in the same suburb. And for every letter we use to write "thanks postie!" on the front of the envelope. Hopefully a postie received our appreciation for keeping us in contact. PS: I'm still great friends with my primary school bestie =)
I haven't utilised Australia Post as much as my pen-palling days until now! This is how all our goods are packaged before trusting it entirely to the postie.
