Thanks for the Enlightenment

I just got an email from my international coordinator Torkel Werge in which he called the exchange students on to hand in their study plan for the spring term (this request doesn't apply to me as I will already be back in Germany at Christmas).

But apart from that he also wrote us the following enlightening sentence:

Some of you may have noticed it is dark outside when you get up in the morning. It is quite normal. It should be like that.
