I'm a student in the university and my major is political science.
I learn German now and hope I will visit there one day.:)
It's cool to know everyone and place even culture by postcard.
You can share a lot of things what is happy ,sad,interesting and memorable...... about your life.
You can introduce your country,too.
It's nice to meet u.:)
You can write"How are you?" in your mother language on the postcard.:)
My biggest dream is to travel all over the world and visit each country at least once :)
