Verb conjugation of "zufrieren" in German

Good luck and success in this new job. Please tell Anna that this morning I had a great Capuchino coffee and I had to think of her. The aroma reminded me of our vacation in Northern Italy.
You have to be careful when you go on summer vacation. There are many dangers but the most dangerous one is the sun itself, because if you're not careful it may harm you. People underestimate the rays.
So this is my last week here in Germany, then it's back to Italy. I'm not sure if I will return soon. But I am longing for friends and family. I will certainly return one day, that is sure.
