Translation of Jahrestag

Hi Christin, how are you? I am on vacation right now, but you can call me if there are any problems. I am planning to meet my students in the end of next week. I will deliver the message anyway.
We begin to talk about 'we' and 'they', which makes us partly discriminating. As a whole, I guess that all of us have some predispositions, but the difference is, that some know how to supress it.
I got a nickname. Please answer the questions from my previous email (below), except number 4, which is answered on the Vocabulix's faq page. I am ready to start tomorrow, but i need the info first.
