About Christian...
Hi!
My name is Christian, and I'm a physics student from northwest Germany. So you can probably guess that I'm somewhat interested in physics, mathematics, astronomy etc. I don't know if there are postcards about these things, but if you have one I'd like to see it!
Otherwise I will be very happy about some photo of the town or region where you live, showing its nature, landscape or architecture. Or just send me a random postcard to surprise me!
I would also be interested in getting messages in many different languages. I must admit that I can't speak all the languages listed above, but I have some friends who can help me. :-)
Best,
Christian
